摘要：A lightweight ready-mix concrete composition that contains 8-20 volumepercent cement, 11-50 volume percent sand, 10-31 volume percent prepuff particles, 9-
40 volume percent coarse aggregate, and 10-22 volume percent water, where the sum ofcomponents used does not exceed 100 volume percent;. The prepuff particles have anaverage particle diameter of from 0.2 mm to 8 mm, a bulk density of from 0.02 g/cc to0.64 g/cc, an aspect ratio of from 1 to 3. The slump value of the composition measuredaccording to ASTM C 143 is from 2 to 8 inches. After the lightweight ready-mix concretecomposition is set for 28 days, it has a compressive strength of at least 1400 psi as testedaccording to ASTM C39.
