More D Although flexural strength cannot be determined for those materials that do not break, tangent modulus of elasticity can be determined. 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. Scope 1. 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.

Flexural Strength and Modulus of Elasticity of Chemical- Resistant Mortars, Grouts, Monolithic Surfacings, and Polymer Concretes1 This standard is issued under the fixed designation C ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
A number in parentheses indicates the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense.
Terminology strength and modulus of elasticity in flexure of cured chemical- resistant materials in the form of molded rectangular beams. Significance and Use or greater , and polymer concretes. These materials shall be based on resin, silicate, silica, or sulfur binders. Although flexural strength cannot be a simple beam in center point loading: the bar rests on two determined for those materials that do not break, tangent supports and the load is applied by means of a loading nose modulus of elasticity can be determined.
No size. Method B covers the testing procedure generally used for attempt has been made to incorporate into this test method all systems containing aggregate from 0.
Method C is used for systems containing aggregate larger material when subjected to actual service. Apparatus safety concerns, if any, associated with its use.
