SOME MAJOR ISSUES OF SELF-COMPACTING CONCRETE

摘要

The development of self-compacting concrete(SCC) is a great achievement for the construction industry and can assist in overcoming problems associated with insitu cast concrete. The skill of workers, and shape and amount of reinforcing bar arrangement of a structure do not affect self-compacting concrete. Due to high-fluidity and resisting power of segregation of self-compacting concrete, it can be pumped longer distances. Self compacting concrete extends the possibility of using various mineral by-products in its manufacture. This paper summarizes some of the latest developments of self-compacting concrete and their relevance. Major issues, such as rheology of fresh concrete and mix design requirements are discussed.
