The relation between initial hydration and strength development of rapid hardening portland cement was studied. The mineral compositions of industrial cements used and their small particle portions were calculated by an improved Bouge's equation. The M1/M3 ratio and amounts of alite reacted for 12 and 24 houres were measuerd by XRD. The microstrucre of cement paste was also observed using a transmission electron microscope(TEM). Alite having a large amount of M1 phase hydrated more quickly up to 24 hours. TEM observations showed that ettringite crystals filled up space between cement particles after 12 hours. The strength of cement pastes increased with increasing amount of alite reached. The volume of ettringite formed after 12 hours may also influence the strength of cement paste for 24 hours curing.
