Standard Test Method for Evaluation of the Effect of Water Repellent Treatments on Freeze-Thaw Resistance of Hydraulic Cement Mortar Specimens

Standard Test Method for Evaluation of the Effect of Water Repellent Treatments on Freeze-Thaw Resistance of Hydraulic Cement Mortar Specimens

ABSTRACT
This test method details the standard procedure for evaluating the effect of water repellent treatments on the freeze-thaw resistance of hydraulic cement mortar specimens. This test method is designed to compare the effectiveness of water repellent treatments under conditions of freezing and thawing only, intended as a laboratory screening method for treatment selection and may not accurately reflect the performance of treated and untreated specimens in the field. This procedure requires the use of a balance, corrosion-resistant aluminum metal pan, weight per litre (gallon) cup, freezing chamber, forced draft oven, and stiff-nylon-bristled brush. Mortar specimens are treated with or immersed in a water repellent material, removed, and allowed to cure. After air drying, the treated specimens are weighed then subjected to various cycles of freezing and thawing. Periodic weighing and observations are made to determine weight loss and deleterious effects such as spalling and cracking.
SCOPE
1.1 This test method covers a procedure for determining the comparative effect of water repellent treatments on the freeze-thaw cycling of hydraulic cement mortar specimens.
1.2 This test method is designed to compare the effectiveness of water repellent treatments under conditions of freezing and thawing only. This test method is intended as a laboratory screening method for treatment selection and may not accurately reflect the performance of treated and untreated specimens in the field. This test method is not intended to duplicate field conditions.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for Linear Shrinkage and Coefficient of Thermal Expansion of Chemical-Resistant Mortars, Grouts, Monolithic Surfacings, and Polymer Concretes

SIGNIFICANCE AND USE
4.1 This test method offers a means of comparing the relative linear shrinkage and coefficient of thermal expansion.  
4.1.1 The material to be tested is placed in the mold in a fluid or plastic state. As the material makes a transition to a solid state, it adheres to and captures the end studs.  
4.1.2 The linear shrinkage measured is the change in length that occurs after the material is rigid enough and strong enough to move the studs.  
4.2 This test method can be used for research purposes to provide information on linear changes taking place in the test materials. Other dimensional changes may occur that do not manifest themselves as changes in length.
SCOPE
1.1 This test method covers the measurement of the linear shrinkage during setting and curing and the coefficient of thermal expansion of chemical-resistant mortars, grouts, monolithic surfacings, and polymer concretes.  
1.2 A bar of square cross-section is cast to a prescribed length in a mold that holds measuring studs that are captured in the ends of the finished casting.  
1.2.1 The change in length after curing is measured and used to calculate shrinkage.
Note 1: Shrinkage determinations should not be made on sulfur mortars, since this test method cannot truly reflect the overall linear shrinkage of a sulfur mortar.  
1.2.2 The change in length at a specific elevated temperature is measured and used to calculate the coefficient of thermal expansion.  
1.3 This test method is limited to materials with aggregate size of 0.25 in. (6 mm) or less.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.5 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.  
1.6 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.

4.2 The results obtained by this test method should serve as a guide in, but not as the sole basis for, selection of a chemical-resistant material for a particular application. No attempt has been made to incorporate into this test method all the various factors that may affect the performance of a material when subjected to actual service.  
4.3 In addition to the tangent modulus of elasticity, a secant modulus is calculated at the point on the stress-strain (load-deflection) graph where the strain is 50 % of the maximum strain.
SCOPE
1.1 This test method covers the determination of flexural strength and modulus of elasticity in flexure of cured chemical-resistant materials in the form of molded rectangular beams. These materials include mortars, brick and tile grouts, structural grouts, machinery grouts, monolithic surfacings (60 mils or greater), and polymer concretes. These materials shall be based on resin, silicate, silica, or sulfur binders.  
1.2 A bar of rectangular cross section is tested in flexure as a simple beam in center point loading: the bar rests on two supports and the load is applied by means of a loading nose midway between supports.  
1.3 Method A outlines the testing procedure generally used for systems containing aggregate less than 0.2 in. (5 mm) in size. Method B covers the testing procedure generally used for systems containing aggregate from 0.2 in. to 0.4 in. (10 mm) in size. Method C is used for systems containing aggregate larger than 0.4 in.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.5 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.  
1.6 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.

Standard Practice for Determination of Major and Minor Elements in Aqueous Pore Solutions of Cementitious Pastes by Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES)

SIGNIFICANCE AND USE
5.1 The chemical composition of the liquid in cementitious pastes is an important indicator of the solid component reactivity at early times, being influenced by the content and rate of reaction of readily soluble alkali components, lime, and other soluble phases. Monitoring the solution composition with time can provide valuable diagnostic information about cement quality and reactivity to supplement other sources of characterization data. This practice is intended to aid in the interpretation of the concentrations of readily soluble components in cement paste solutions, which may include portland cement, limestone, fly ash, ground granulated blast furnace slag, or other components. It provides guidance for measuring the time dependence of the concentrations of one or more components, on an elemental basis, including, but not limited to, aluminum, calcium, potassium, silicon, sodium, and sulfur.
SCOPE
1.1 This practice describes a procedure for collection, sample preparation and analysis of aqueous pore solutions obtained from cementitious materials at different hydration times when analyzed by ICP-OES for the six most common readily soluble elements aluminum, calcium, potassium, silicon, sodium and sulfur.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 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.  
1.4 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.
