Self-consolidating concrete (SCC) is a highly flowable, non-segregating concrete mix that when used correctly, reduces labor, time, and the possible source of technical and quality control issues. Because this concrete mix prevents voids and honeycombing, it is commonly used in structural and architectural concrete elements where surface smoothness is important.

When poured, proper SCC flows very easily with and around the framework to closely follow the shape and surface texture of the mold. By testing self-consolidating concrete, you can eliminate it’s flowability and therefore the need for vibrating or tamping after the initial pour.

Self-consolidating concrete should be tested for flow rates, passing ability, levels of aggregate segregation resistance, and filling evaluation. SCC is designed in such a way that compaction and a high proportion of water are not required to become fluid. Therefore, initial testing is vital to lasting success.
