Jun 17, 2019·Self-compactingconcretewith a similar water cement or cement binder ratio will usually have a slightly higherstrengthcompared with traditional vibratedconcrete, due to the lack of vibration giving an improved interface between the aggregate and hardened paste. Theconcretemix of SCC must be placed at a relatively higher velocity than that of regularconcrete.Get Price

Self-compactingconcrete(SCC) It uses superplasticisers and stabilisers to significantly increase the ease and rate of flow. It achieves compaction into every part of the mould or formwork simply by means of its own weight without any segregation of the coarse aggregate.Get Price
Testing. Severaltestprocedures have been successfully employed to measure the plastic properties ofSelf-ConsolidatingConcrete. The slump flowtest, using the traditional slump cone, is the most common fieldtestand is in the process of being standardized by ASTM.Get Price
Freshself-compactingconcrete(SCC) flows into place and around obstructions under its own weight to fill the formwork completely andself-compact, without any segregation and blocking. The elimination of the need for compaction leads to better qualityconcreteand substantial improvement of working conditions.
