Standard Test Method for Determination of Water/Cementitious Materials Ratio for Geosynthetic Cementitious Composite Mats (GCCMs) and Measurement of the Compression Strength of the Cementitious Material Contained Within
|Publication Date:||1 June 2020|
The purpose of the proposed test method is to obtain a water/cementitious material ratio that allows for a practical measurement of the compressive strength of the cementitious material contained within a geosynthetic cementitious composite mat (GCCM). This water/cementitious material ratio should be generally representative of that achieved practically upon the hydration of a GCCM. Because GCCM materials do not involve mixing or the use of exact water hydration methods when employed in the field, this method is necessary to provide a quantitative estimate of the water/cementitious material ratio.
This procedure determines the water/cementitious material ratio for a properly hydrated GCCM, which is then used to create cube or cylinder specimens for compressive strength testing as per the appropriate referenced ASTM test methods. Compressive strength results will then be representative of the strength of the inherent cementitious material found in the GCCM after normal GCCM hydration.
The values in SI units are to be regarded as standard. Values in inch-pound units are in parentheses for information.
