简介：包括石灰石，沙的六代表性的父母岩石石英岩，片麻岩，花岗石，暗岩和大理石被选择在可使用性，机制性质，体积稳定性和制造沙水泥的耐久性上在生产的沙的各种各样的岩性学的效果上进行系统的研究。试验性的结果证明制造沙水泥的力量比自然沙的水泥的稍微高。而且，分别地与六不同岩性学石头粉末的相等的数量代替具体混合的15%水泥，数据显示他们能改进水泥可使用性，推迟塑料裂开时间，提高击碎反的等级，并且没在防冻剂和硫酸盐攻击抵抗的性质上有明显的效果，但是减少能力抵抗氯化物离子穿入。而且，在生产的沙和石头粉末的各种各样的岩性学引起的水泥可使用性，机制性质，体积稳定性和耐久性的差别不是重要的，水泥的宏性质上的岩性学变化的影响能最后被忽视。
