摘要：

The study was conducted on the effects of Cr2O3, Fe2O3, Cu(OH)2, ZnO and Pb2O(OH)2 on the formation of ettringite and microstructure of hardened ettringite. The cement samples were prepared by mixing C3A synthesized and CaSO4·2H2O and adding 5 % by weight of above additives. The heavy metal oxides and hydroxides promote the crystal growth of ettringite and produce some changes in microstructure and Cr2O3 and Cu(OH)2 exert a considerable influence. © 1979.
