Abstract

The phenomena that excess sulfate hindred the C3S formation in the presence of clinker liquid phase were investigated. In the case of (NH4)2SO4, assuming SO3 atmospheric condition, sulfate stabilized C2S and was enriched at the surface of C2S grains, so C2S was prevented from being dissolved into clinker melt. CaSO4 showed the similar aspect with (NH4)2SO4, however, the prevention of C3S formation by CaSO4 took more influence that C2AS and C4A3 were formed below 100$0^{\circ}C$, and remained upto clinkering temperature, 145$0^{\circ}C$, thus these intermediate phases caught CaO which would participate the C3S formation.
