ASTM C270, is almost similar to EN 1015-11, but size of the specimens may change.
In
the below video, soil shrinkage is tested. Similarly, for other products can be
tested by adopting the mixing ratio and process.
Flexural Strength and Modulus of Elasticity of Chemical-Resistant Mortars, Grouts, Monolithic Surfacings, and Polymer Concretes ASTM C580-02(2012):
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.
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.
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 to 0.4 in. (10 mm) in size.
Method C is used for systems containing aggregate larger than 0.4 in.
Let see what does BS 6319 says:
