Workability Evaluation of Self Compacting Concrete
The compactibility, mobility and segregation stability of self compacting concrete (SCC) is essential for its quality control. Completely and reasonably workability evaluation to SCC has an obviously influence in concrete engineering field. The paper introduced the rheology and workability mechanism of SCC. Ten workability assessment methods, such as Slump Flow test, U-box test, J-ring test, L-box test, VSI method, Oriment test, V-funnel test, Inverted Slump Cone test, were presented and the advantages and disadvantages of each appraisal procedure and the evaluation practice were analyzed. It also put forward the prospect direction of workability evaluation of SCC.
