THE INFLUENCE OF CEMENTITIOUS SYSTEMS TO CRACKING SENSITIVITY OF SELF-COMPACTING CONCRETE
Self-Compacting Concrete(SCC)has high potential for wider structural applications in new buildings and reinforcement projects as its outstanding workability and good durability.Compared with conventional concrete,typical Self-Compacting Concrete mixture involves high amounts of binder,high dosage of superplasticizer and complex binder components,and these affects the early age cracking sensitivity of SCC to some extent.In this paper the experimental research on cracking sensitivity of SCC cementitious systems by ring test is described.The cracking sensitivity is evaluated by the age when cracks occur.The ratio of water to cement,type and content of mineral fillers such as fly ash and blast furnace slag(BFS),type and dosage of superplasticizer,varieties of cement are considered as the main factors in this paper.The results help to find how these parameters affect the cracking sensitivity of SCC and give some advice for SCC mix design.
