玄武岩石粉和超细砂对水泥砂浆强度性能影响的试验研究
发布时间:2021-07-03 22:04
硅酸盐水泥作为一种最常用的胶凝材料,在世界范围内被广泛应用于各种水泥基材料的制备。当硅酸盐水泥与水和细集料一起混合时,所得的混合物称为水泥砂浆。细骨料可有多种类型,但最常用的是河砂。此外,破碎的岩石细粒和机制砂也可用作细集料。但是,在最近几十年中,建筑材料的生产一直依赖于自然资源,由于硅酸盐水泥制造业的粗放化和对自然资源过渡的开采,导致出现了严重的环境和经济问题。水泥的生产一般会产生大量的二氧化碳(CO2),这些二氧化碳会直接排放到大气中。当大气中存在的大量二氧化碳含量上升时,会对地球的生态系统产生严重的影响。而造成环境恶化的另一个因素是没有充分利用自然资源生产矿物集料,这个原因在其中一些地区已经成为环境恶化的主要原因。传统方法的现代化改进和推广可持续、环境友好型的建筑材料成为目前建筑材料领域的发展趋势。许多新型环保建筑材料已经应用于实际工程,还有一些新型建筑材料也在性能评估的过程中。土木工程材料的发展有两个主要因素,一是因为需要为全世界的居民提供基本且必要的基础设施,二是政府为了保护环境和生态平衡而出台的一系列的限制条件。由于技术的进步,现代水泥基复合材料与传统...
