The concrete composition contains less than 30 volume percent of other light weighting aggregates and the prepuff particles have an average particle diameter of from 0.2 mm to 8 mm, a bulk density of from 0.02 g/cc to 0.64 g/cc, an aspect ratio of from 1 to 3. The slump value of the placed concrete measured according to ASTM C 143 is greater than 1 inch and the concrete has a density of from about 40 to about 135 lb./ft 3 .

Abstract: Methods of controlling the durability of and/or the amount of air in concrete formulations that include combining cement, water, and optionally aggregates, admixtures and/or additives to form a cement mixture; and adding prepuff particles to the cement mixture to form a concrete formulation. The prepuff particles have an average particle diameter of from 0.2 mm to 3 mm, a bulk density of from 0.015 g/cc to 0.35 g/cc, an aspect ratio of from 1 to 3, and a smooth continuous outer surface. The cured and hardened concrete formulation typically has a relative dynamic modulus of at least 70% determined according to Procedure A of ASTM C666 (2003). The amount of air in the concrete typically increases over the amount of air in similar formulations not containing prepuff particles, as determined according to ASTM C231, based on the volume percent of prepuff. The concrete formulations can be used to make articles.

Abstract: A method of reducing plastic shrinkage cracking in concrete compositions that includes a) combining 3 -40 volume percent cement, 5 - 50 volume percent fine aggregate, 5 - 50 volume percent coarse aggregate, and 10 - 22 volume percent water to form a concrete mixture; b) during or after (a), adding 1.5 - 40 volume percent of prepuff particles to the concrete mixture to form a concrete composition; c) placing the concrete composition in a form; and d) allowing the concrete to set and harden to form a hardened concrete article substantially free of plastic shrinkage cracking. The prepuff particles have an average particle diameter of from 0.2 mm to 8 mm, a bulk density of from 0.02 g/cc to 0.64 g/cc, an aspect ratio of from 1 to 3. The concrete composition has a density of from about 40 to about 135 lb./ft 3 .
