ASTM International Committee C09 on Concrete and Concrete Aggregates has recently approved two new standards, C 1611, Test Method for Slump Flow of Self-Consolidating Concrete, and C 1622, Specification for Cold-Weather Admixture Systems. Descriptions of both new standards follow. , C 1611 Test Method for Slump Flow of Self-Consolidating Concrete, The concrete industry has been using self-consolidating concrete for the past several years. A new ASTM International standard developed by Committee C09 on Concrete and Concrete Aggregates, C 1611, Test Method for Slump Flow of Self-Consolidating Concrete, will allow users to measure the consistency of self-consolidating concrete for the first time. "Because of its high fluidity, the…, C 1622 Specification for Cold-Weather Admixture Systems, Using concrete during construction in cold weather is difficult since concrete can freeze before it hardens. However, a new ASTM standard, which is the result of a project to prove that antifreeze technology for concrete is feasible, will allow for greater use of concrete during construction in cold weather. ASTM Committee C09 on Concrete and Concrete Aggregates has approved the new standard…
