Standard Practice for Preparing Coupons for Flexural and Washout Tests on Glass Fiber Reinforced Concrete

SIGNIFICANCE AND USE
3.1 Flexural strengths, as determined by Test Method C947, are used for quality control and design of GFRC products and may be used to verify compliance with specifications and to collect data in research and development programs. It is, therefore, important that coupons be prepared according to a standard practice. The coupons are used to make test specimens for Test Method C947 and for Test Method C1229 to determine the amount of glass fiber reinforcement per unit volume of GFRC for quality control purposes.
SCOPE
1.1 This practice covers preparation of test coupons to be used in tests of plant manufactured thin-section glass fiber reinforced concrete (GFRC).  
1.2 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.  
1.3 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.

ASTM C948-81(2023)(Test Method)
Standard Test Method for Dry and Wet Bulk Density, Water Absorption, and Apparent Porosity of Thin Sections of Glass-Fiber Reinforced Concrete

SIGNIFICANCE AND USE
2.1 Material properties determined by this test method are useful for quality control of glass-fiber reinforced concrete, ascertaining compliance with governing specifications, and research and development.
SCOPE
1.1 This test method covers the determinations of dry and wet bulk density, water absorption, and apparent porosity of thin sections of glass-fiber reinforced concrete.  
Note 1: This test method does not involve a determination of absolute specific gravity. Therefore, such pore space as may be present in the specimen that is not emptied during the specified drying or is not filled with water during the specified immersion is considered “impermeable” and is not differentiated from the solid portion of the specimen for the calculations, especially those for percent voids.
Depending upon the pore size distribution and the pore entry radii of the specimen and on the purposes for which the test results are desired, the procedures of this method may be adequate, or they may be insufficiently rigorous. In the event that it is desired to fill more of the pores than will be filled by immersion, various techniques involving the use of vacuum treatment or increased pressure may be used. If a rigorous measure of total pore space is desired, this can only be obtained by determining absolute specific gravity by first reducing the sample to discrete particles, each of which is sufficiently small so that no impermeable space can exist within any of the particles.  
1.2 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.  
1.3 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.

ASTM C1560-03(2023)(Test Method)
Standard Test Method for Hot Water Accelerated Aging of Glass-Fiber Reinforced Cement-Based Composites

SIGNIFICANCE AND USE
3.1 The basis for this test as an indicator of the long term behavior of fiber reinforced composites is that elevated temperature and moisture content accelerate the formation of the products of hydration of the cement in the matrix, particularly calcium hydroxide.  
3.1.1 It is known that the interaction of these products of hydration, particularly calcium hydroxide, with the fibers can have a major effect on the long-term properties of the composites.  
3.1.2 The principal mechanism that occurs is that the calcium hydroxide forms within the bundles of filaments that form the glass fiber strand. This gradually bonds the filaments together, which reduces filament pull-out. This causes a reduction in the strain capacity of the composite, thereby reducing the strength of the composite and changing the composite from a ductile material to an increasingly brittle material.  
3.1.3 Accelerating the formation of the hydration products accelerates their interaction with the fibers, hence accelerating the aging of the composite.  
3.2 The data developed from this test are used by researchers and manufacturers to evaluate the long-term performance of different mixtures, reinforcements, mixture components, and to provide data for the development of design procedures for products made from these composites.  
3.2.1 The recorded data also provides screening information as new matrices and reinforcements are developed.  
3.3 The usefulness of the test as an indicator of long term composite performance is valid if the only reactions that are accelerated are those that occur more slowly under natural weathering, hot water can induce effects in some composites, for instance those containing acrylic polymer, that may not occur in natural weathering. This test method may not be a valid indicator of long-term performance of such composites.
SCOPE
1.1 This test method provides a way of accelerating the aging of glass fiber reinforced cementitious composites in order to develop data that will indicate real-life natural weathering performance.  
1.2 The coupons prepared for this test method will be tested using Test Method C947.  
1.3 This test method can be used to age coupons for other test methods.  
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.
