| Abstract: | On the base of the rheology of flesh concrete and the characteristic of self-closely-concrete(SCC) ,the influence of fly ash on the rheological behavior of SCC is presented in this paper. The function mechanism of fly ash in bleeding, segregation and slump loss of concrete is also analyzed. At last, the measures are put forward to improve the working performance of SCC. |
