Standard Test Method for Bond Strength of Bonding Systems Used With Concrete By Slant Shear
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.
