Compressive Strength of Chemical-Resistant Mortars

As per ASTM C 579, test methods cover the determination of the compressive strength of chemical-resistant mortars, grouts, monolithic surfacing, and polymer concretes. These materials may be based on resin, silicate, silica, or sulphur binders.

There are 3 methods are explained in this standard:

Test Method A - outlines the testing procedure generally used for systems containing aggregate less than 0.0625 in. (1.6 mm) in size. Moulds size shall be right cylinder of 25mm in diameter by 25mm high are tested

Test Method B - covers the testing procedure generally used for systems containing aggregate from 0.0625 to 0.4 in. (1.6 to 10 mm) in size. Moulds size of 50 mm cube are tested.

Test Method C - is used for systems containing aggregate larger than 0.4 in. Moulds shall be right cylinders diameter shall be at least four times the nominal maximum aggregate size in the mix, but minimum cylinder diameter shall be 50 mm. The cylinder height shall be two times the diameter.

Filling and Capping for top with Resin, Silica, and Silicate Specimens—The top layer may be filled to slightly below the top edge of the mould except for sulphur materials.
