ASTM-C905 2006

1.1 These test methods cover the procedures for determining the uncured (wet) and conditioned (dry) densities of resin, silicate, silica, and sulfur-based chemical-resistant mortars, grouts, monolithic surfacings, and polymer concretes.

1.2 Mold Method A outlines the molding procedure generally used for systems containing aggregate less than 0.2 in. (5 mm) in size. Mold Method B covers the molding procedure generally used for systems containing aggregate from 0.2 to 0.4 in. (10 mm) in size. Mold Method C is for systems containing aggregate larger than 0.4 in.

1.3 Density Method I: Apparent Uncured Density of Resin, Silica, and Silicate MaterialsThis test method is not applicable to sulfur materials.

1.4 Density Method II: Apparent Conditioned Density of Resin and Sulfur-based MaterialsThis test method may be applicable to silica or silicate materials if they are not water-sensitive.

1.5 Density Method III: Apparent Conditioned Density of Silica and Silicate Materials that are Water Sensitive
