The preparation method of 8-C2S without stabilizer, and their hydration characteristics were studied. 8-C2S is formed when y-C2S is heated at about 1000°C or about 1500\*C. The hydration kinetics of 8-CaS produced from ~'-CaS is markedly different from that from ephase. Ca(OH) 2 is hardly produced
The final hydrated product of B-C2S is identical to the natural mineral tobermorite 5CaO. 6SiO.5-7H20 and not the tobermorite-like phase 3CaO. 2SiOp.3HgO as stated earlier . The mechanism of the hydration react -ion is f~llo~ed up to 3.5 years. The suggested mechanism is based on the extraction of t
Small quantities (<2%) of various metal oxides are incorporated into the lattice of ~-C2S during the high temperature preparation. The effect which these stabilizers have on the hydration rate is examined. A model involving the charge/radius ratio of the metal ion is developed to explain altered hyd
