澳大利亚联邦科学与工业研究组织建筑研究部和意大利的那波里斯大学协作,最近研制成功一种新型水泥,这种水泥是一种钙矾石基的水硬性胶结材料。这种钙矾石基水泥的最重要特性是其不需要象波特兰水泥那样要求高代价的高温煅烧工艺,它只需要用一些含有硫酸盐、氧化铝、氧 In collaboration with the Building Research Department of the Commonwealth Scientific and Industrial Research Organization of Australia and the University of Naples, Italy, a new type of cement has recently been developed. This cement is an ettringite-based hydraulic cementing material. The most important characteristic of this type of ettringite-based cement is that it does not require a high-cost high-temperature calcining process like Portland cement. It only needs to use some sulphate, alumina and oxygen.
