一、硫酸盐矿渣水泥概述硫酸盐矿渣水泥具有强度高(试验室中利用石景山矿渣已能制得500号以上的水泥)抗蚀性强、水化热低及体积收缩小等优良性能。而生产设备简单,成本低。可与矽酸盐水泥相比美的水硬性胶结材料。硫酸盐矿渣水泥是利用经水淬后的粒状高炉矿渣(约80%)和煆烧石膏(约15%)加入少量碱性介质(石灰或水泥熟料),按适当配比共同磨制而成.由于这种水泥在我国还是一种新产品,它的特性还没有被使用者所熟识,在工程上使用还缺乏经验,因此它的优良性能没有被充分发挥而它的一些缺点(如凝结缓慢及起
First, an overview of sulfate slag cement Sulfate slag cement with high strength (laboratory use of Shijingshan slag has been able to produce more than 500 cement) corrosion resistance, low heat of hydration and small volume shrinkage and other excellent performance. The production equipment is simple, low cost. Usable with Portland cement hydraulic cementing materials. Sulfate slag cement is obtained by adding a small amount of alkaline medium (lime or cement clinker) into granulated blast furnace slag (about 80%) and burnt gypsum (about 15%) after water quenching, and grinding them together according to an appropriate ratio Because this kind of cement is still a kind of new product in our country, its characteristic has not been acquainted with by user yet, it is inexperienced to use in engineering, so its excellent performance is not fully exerted but some of its shortcomings And from
