DURABILITY OF SELF-COMPACTING CONCRETE(SCC)

摘要：

The research of SCC especially under the effect dof cyclic freeze and thaw process and in combination of freezing with chemical defrosting substances is not too much described in profesional publications.This paper is concerned with the manufacture problem of self-compacting concrete,containing special aerating additives to achieve values usual with normal aerated concrete.The test methods for determining the rheology of fresh SCC are described including the determination of aeration measure.Further the results received in tests with hardened concrete are published - compression strength,E-moduli.Mainly the durability was checked by frost resistance measuring methods and under the effect of chemical defrosting salts.In the way the possibility of utilization of SCC even in climatically demanding conditions was proved.
