Description

Self-consolidating concrete (SCC) has been successfully used in many projects around the world and has made a major impact on concrete placement and construction economics. This report contains the current state of knowledge with respect to SCC. The information in this document is expected to inform concrete producers, users, and specifiers of SCC of known practices and processes. Because SCC is a viable solution to various concrete placement problems, ASTM has established Subcommittee C09.47, Self-Consolidating Concrete, to develop standard test methods for SCC.

Keywords: admixture; aggregate; air entrainment; bleeding; ement;consolidation; curing; placing; self-consolidating concrete; specification;viscosity, workability.
