STUDY ON OPTIMUM MIX PROPORTION OF HIGHLY CONTAINING FLY ASH SILICA FUME CEMENT FOR LOW ALKALINITY

Abstract

Low alkalinity cement is considered desirable as cementitious materials applied for radioactive waste disposal facilities. We investigated optimum mix proportion of highly containing fly ash silica fume cement which is considered as one of the low alkalinity cements from the point of view of low alkalinity, compressive strength and economic efficiency. As a result, it was suggested that OPC：SF：FA＝36～40：12～16：44～48 is candidate for optimum mix proportion in this study. Therefore, we could suggest these mix proportion with economic advantages which had silica fume content reduced, having the required performance as low alkalinity cement equivalent to the conventional basic mix proportion.
