C09.25 - Organic Materials for Bonding

ABSTRACT
This test method covers the determination of the bond strength of epoxy-resin-base bonding systems for use with Portland-cement concrete. The test method covers bonding hardened concrete to hardened or freshly-mixed concrete. The bond strength is determined by using the epoxy system to bond together two equal sections of Portland-cement mortar cylinder. After suitable curing of the bonding agent, the test is performed by determining the compressive strength of the composite cylinder. Apparatus to mix Portland-cement mortar shall be as described, except for the sections on specimen molds, tamper, and testing machine. The molds shall be constructed in the form of right cylinders. A dummy section shall be machined of a hard material that is not attacked by Portland-cement mortar. The testing machine shall be as described. Laboratory conditions, materials, proportions, and procedures for mixing the Portland-cement mortar shall be tested to meet the requirements specified.
SIGNIFICANCE AND USE
5.1 The strength developed by a bonding system that joins two regions of concrete is its most important property.
SCOPE
1.1 This test method covers the determination of the bond strength of bonding systems for use with portland-cement concrete. This test method covers bonding hardened concrete to hardened or freshly-mixed concrete.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.3 The text of this standard refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. A specific hazard statement is given in Section 9. (Warning —Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to exposed skin and tissue upon prolonged exposure.2)  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 This test method applies to materials used in making epoxy-mortar overlays for concrete pavement. If debonding occurs between the overlay and the pavement, the material is unsuitable.  
5.2 This test method evaluates the ability of an overlay to remain bonded to a concrete substrate during repeated thermal cycling in air over a significant temperature range and is not intended to duplicate temperature fluctuations in the field.
SCOPE
1.1 This test method covers the determination of which epoxy-resin formulations are subject to debonding when used as overlays for concrete when the combination of the two is subjected to temperature changes that may be met in the field.  
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the specification.

ABSTRACT
This specification covers two-component, epoxy-resin bonding systems for application to Portland-cement concrete, which are able to cure under humid conditions and bond to damp surfaces. The epoxy-resin bonding systems are classified according to type, grade, class, and color. The bonding systems can be classified as Type I, Type II, Type III, Type IV, Type V, Type VI, and Type VII according to their physical requirements. According to their flow characteristics and viscosity, the bonding systems can be classified as Grade 1, Grade 2, and Grade 3. Also, in accordance with the range of temperatures for which they are suitable, these materials can be designated as Class A, Class B, Class C, Class D, Class E, and Class F. Classes A, B, and C are defined for Types I through V, and Classes D, E, and F are defined for Types VI and VII. Epoxy resin systems are normally unpigmented, but they can be colored or darkened. These bonding systems shall be furnished in two components for combining immediately prior to use in accordance with written instructions formulated Component A shall contain an epoxy resin with or without a reactive diluent. Component B shall contain one or more curing agents, which on mixing with Component A shall cause the mixture to harden. A suitable inert filler may be uniformly incorporated in one or both components. The filler shall be either nonsettling or readily dispersible in any component in which it is incorporated. All systems shall cure under humid conditions, and bond to damp surfaces. Different test methods shall be performed to determine the following properties: consistency, gel time, filler content, epoxy equivalent, viscosity, absorption, bond strength, thermal compatibility, heat deflection temperature, linear coefficient of shrinkage, compressive yield strength and modulus, tensile strength and elongation at break, and contact strength.
SCOPE
1.1 This specification covers two-component, epoxy-resin bonding systems for application to portland-cement concrete, which are able to cure under humid conditions and bond to damp surfaces.  
1.2 This specification does not cover epoxy-resin-base bonding systems that have been modified by addition of components such as cement, fine aggregate, or fiber reinforcement. Additional testing may be required to meet applicable specifications for these applications.  
1.3 This specification does not address the effects of creep on epoxy-resin-base bonding systems while under load or the potential for creep rupture. Additional testing is required for applications where creep and creep rupture are critical.  
1.4 The text of this standard refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard.  
1.5 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

ABSTRACT
This specification covers standard test method for tensile strength of concrete surfaces and the bond strength or tensile strength of concrete repair and overlay materials by direct tension (pull-off method). This test method is suitable for both field and laboratory use to determine one or more of the following: the near-surface tensile strength of the substrate as an indicator of the adequacy of surface preparation before application of a repair or overlay material; the bond strength of a repair or an overlay material to the substrate; and the tensile strength of a repair or overlay material, or an adhesive used in repairs, after the material has been applied to a surface. The following apparatus shall be utilized: core drill; core barrel; steel disk; tensile loading device; and a coupling device. This test shall be performed on the surface of a prepared concrete base before application of a concrete repair overlay material, or on the surface of a concrete repair overlay material after the material has been applied to the prepared concrete surface. The test specimen shall be formed by drilling a shallow core into and perpendicular to the surface of the substrate, and leaving the intact core attached to the concrete. A steel disk shall be bonded to the top surface of the test specimen. A tensile load shall be applied to the steel disk until failure occurs. The failure load and the failure mode shall be recorded and the nominal tensile stress at failure shall be calculated.
SIGNIFICANCE AND USE
5.1 This test method determines the tensile strength of concrete near to the prepared surface, which can be used as an indicator of the adequacy of surface preparation before applying a repair or an overlay material.  
5.2 When the test is performed on the surface of a repair or an overlay material, it determines the bond strength to the substrate or the tensile strength of either the overlay or substrate, whichever is weaker.  
5.3 The method may also be used to evaluate the adhesive strength of bonding agents.  
5.4 When the test is performed on the surface of a material applied to the substrate, the measured strength is controlled by the failure mechanism requiring the least stress. Thus it is not possible to know beforehand which strength will be measured by the test. For this reason, the failure mode has to be reported for each individual test result, and tests results are averaged only if the same failure mode occurs.
SCOPE
1.1 This test method is suitable for both field and laboratory use to determine one or more of the following:  
1.1.1 The near-surface tensile strength of the substrate as an indicator of the adequacy of surface preparation before application of a repair or overlay material.  
1.1.2 The bond strength of a repair or an overlay material to the substrate.  
1.1.3 The tensile strength of a repair or overlay material, or an adhesive used in repairs, after the material has been applied to a surface.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.3 The text of this standard refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision o...

SIGNIFICANCE AND USE
5.1 When the test is performed on the repair or overlay material, the result is the bond strength to the concrete panel or the tensile strength of either the overlay or concrete panel, whichever is weaker.  
5.2 The measured strength is controlled by the failure mechanism requiring the least stress. Thus, it is not possible to know beforehand which strength will be measured by the test. For this reason, the failure mode has to be reported for each individual test result, and tests results are averaged only if the same failure mode occurs. Alternatively, one can infer that the bond strength is greater than the failure stress if the bond does not fail during the test.  
5.3 The method may also be used to evaluate the performance of bonding agents.  
5.4 This test method is designed to evaluate bond strengths in the laboratory and to standardize conditions that permit comparison of results between laboratories. It is not intended to determine bond strength for field applications as results obtained are only applicable to the standard substrate.
SCOPE
1.1 This test method is suitable for laboratory use to determine one or more of the following:  
1.1.1 The bond strength of a repair or an overlay material to a specific concrete substrate.  
1.1.2 The tensile strength of a repair or overlay material after the material has been applied to the concrete substrate.  
1.1.3 The change in bond strength when applying a bonding agent or other bond modifying treatment to the concrete substrate.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. Some values have only SI units because the inch-pound equivalents are not used in practice.  
1.2.1 If required results obtained from another standard are not reported in the same system of units as used by this test method, it is permitted to convert those results using the conversion factors found in the SI Quick Reference Guide.2  
1.3 The text of this test method refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this test method.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.)3

5.2 When the test is performed on the surface of a repair or an overlay material, it determines the bond strength to the substrate or the tensile strength of either the overlay or substrate, whichever is weaker.  
5.3 The method may also be used to evaluate the adhesive strength of bonding agents.  
5.4 When the test is performed on the surface of a material applied to the substrate, the measured strength is controlled by the failure mechanism requiring the least stress.

ABSTRACT
This specification covers standard test method for tensile strength of concrete surfaces and the bond strength or tensile strength of concrete repair and overlay materials by direct tension (pull-off method). This test method is suitable for both field and laboratory use to determine one or more of the following: the near-surface tensile strength of the substrate as an indicator of the adequacy of surface preparation before application of a repair or overlay material; the bond strength of a repair or an overlay material to the substrate; and the tensile strength of a repair or overlay material, or an adhesive used in repairs, after the material has been applied to a surface. The following apparatus shall be utilized: core drill; core barrel; steel disk; tensile loading device; and a coupling device. This test shall be performed on the surface of a prepared concrete base before application of a concrete repair overlay material, or on the surface of a concrete repair overlay material after the material has been applied to the prepared concrete surface. The test specimen shall be formed by drilling a shallow core into and perpendicular to the surface of the substrate, and leaving the intact core attached to the concrete. A steel disk shall be bonded to the top surface of the test specimen. A tensile load shall be applied to the steel disk until failure occurs. The failure load and the failure mode shall be recorded and the nominal tensile stress at failure shall be calculated.
SIGNIFICANCE AND USE
This test method determines the tensile strength of concrete near to the prepared surface, which can be used as an indicator of the adequacy of surface preparation before applying a repair or an overlay material.
When the test is performed on the surface of a repair or an overlay material, it determines the bond strength to the substrate or the tensile strength of either the overlay or substrate, whichever is weaker.
The method may also be used to evaluate the adhesive strength of bonding agents.
When the test is performed on the surface of a material applied to the substrate, the measured strength is controlled by the failure mechanism requiring the least stress. Thus it is not possible to know beforehand which strength will be measured by the test. For this reason, the failure mode has to be reported for each individual test result, and tests results are averaged only if the same failure mode occurs.

ABSTRACT
This specification covers two-component, epoxy-resin bonding systems for application to Portland-cement concrete, which are able to cure under humid conditions and bond to damp surfaces. The epoxy-resin bonding systems are classified according to type, grade, class, and color. The bonding systems can be classified as Type I, Type II, Type III, Type IV, Type V, Type VI, and Type VII according to their physical requirements. According to their flow characteristics and viscosity, the bonding systems can be classified as Grade 1, Grade 2, and Grade 3. Also, in accordance with the range of temperatures for which they are suitable, these materials can be designated as Class A, Class B, Class C, Class D, Class E, and Class F. Classes A, B, and C are defined for Types I through V, and Classes D, E, and F are defined for Types VI and VII. Epoxy resin systems are normally unpigmented, but they can be colored or darkened. These bonding systems shall be furnished in two components for combining immediately prior to use in accordance with written instructions formulated Component A shall contain an epoxy resin with or without a reactive diluent. Component B shall contain one or more curing agents, which on mixing with Component A shall cause the mixture to harden. A suitable inert filler may be uniformly incorporated in one or both components. The filler shall be either nonsettling or readily dispersible in any component in which it is incorporated. All systems shall cure under humid conditions, and bond to damp surfaces. Different test methods shall be performed to determine the following properties: consistency, gel time, filler content, epoxy equivalent, viscosity, absorption, bond strength, thermal compatibility, heat deflection temperature, linear coefficient of shrinkage, compressive yield strength and modulus, tensile strength and elongation at break, and contact strength.

1.1 This specification covers two-component, epoxy-resin bonding systems for application to portland-cement concrete, which are able to cure under humid conditions and bond to damp surfaces.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Some values have only SI units because the inch-pound equivalents are not used in practice. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with this standard.

SIGNIFICANCE AND USE
The bonding properties of adhesives are important for concrete repair applications. This test method provides a means to measure the adhesive characteristics of materials used to bond freshly mixed mortar to hardened concrete.
In addition to providing information on bond strength, the location of failure is determined visually and is thus instructive regarding the weakest element in the composite tested.
The bond strength that is measured is limited by the tensile strength of the base concrete and mortar. While an attempt has been made to choose materials that are strong enough to force a bond failure, there may be cases where failure occurs in concrete or mortar. In these situations, the actual bond strength exceeds the measured result.
