The kinetics of the hydration process of the sulphoaluminate phase Ca4(A16012)(SO 4) in the presence of calcium hydroxide and gypsum were studied by differential calorimetry, optical microscope and X-ray phase analysis. The f'trst period of reaction is characterized by the presence of ettringite eve

The formation of ettringite was investigated by isothermal calorimetry over the range of temperature from 50 to 70Β°C. Ettringite was formed using three sources of alumina: tricalcium aluminate, high alumina cement and calcium aluminate sulfate. In accord with a diffusionally controlled reaction mech
The study was conducted on the effects of Cr203, Fe20 ~, Cu(OH)2,ZnO and Pb20(OH) 2 on the formation of ettringite and miEr6structure of hardened ettringite. The cement samples were prepared by mixing C~A synthesized and CaSO4.2H20 and adding 5 % by weight of above additives The heavy metal oxides
