These production sizes can be sold "as is," but more often are blended before loading to meet appropriate industry specifications.

For producing pumpable structural lightweight concrete, both coarse and fine blends are normally stockpile saturated at the concrete producer's plant. We recommend a seven to ten day soaking period, or longer if possible, for optimum pumpability.

(a) ASTM C 127 / C 128, bulk specific gravity.
(b) ASTM C 29, loose unit weight (density) @ normal 6% shipping moisture content.

(c) ASTM C127 / C 128, 24 hour water absorption at ambient pressure. Please note that the 24 hour absorption figure is not appropriate for use in determining moisture content of Buildex used in pumped concrete.
(d) Unit Weight (density) when stockpile ambient saturated for 7 to 14 days for concrete pump placement.

Buildex aggregate is produced to meet or exceed applicable industry standards, including ASTM C330 "Standard Specification for Lightweight Aggregates for Structural Concrete" and ASTM C 331 "Standard Specification for Lightweight Aggregates for Concrete Masonry Units."
