STRENGTH AND HYDRATION HEAT PROPERTIES OF THE BLAST FURNACE SLAG CEMENT USING HIGH C₃A CLINKER WITH VARIOUS AMOUNT OF C₃S CONTENT

Abstract

In this study, high C₃A clinker with various amount of C₃S was prepared experimentally, and strength and adiabatic temperature rise of blast furnace cement （BFC） prepared with these clinkers were investigated. The 28 days strength of BFC with high C₃A clinker （C₃A：13～16％） was lower than those with the conventional C₃A clinker （C₃A：9～10％）. To improve 28 days strength of high C₃A type BFC, increasing of C₃S or Blaine specific surface area, addition of limestone, and using of TIPA were effective. However, these methods, except for the addition of limestone, also increased the adiabatic temperature rise of BFC.
