Abstract

In order to enlarge effection use as well as to use as a cheafut raw material for high-strength concrete admixture, we manufactured high strength admixture by using various industrial by-products and then applied to 2nd concrete pro when concrete was added MSS, strength of concrete was promoted and had a excellent property than domestic D admixture. This result could be explained that adding of MSS accelerated the famat of ettringite($C_3A$, $3CaSO_4$, $32H_2O$) like needle crystal in steam curing a also promoted to cement solidification and shorten high pre-strength display. As a result of, strength of concrete added MSS pretented, above 850kgf/$\textrm{cm}^2$ in 7 days of long-period curing.
