混凝土是以水泥为主要材料,粉煤灰和其他矿物质为辅料的胶凝材料,与水、粗细骨料,必要时加入外加剂按一定比例关系配合,拌制成的混合物,经过凝结硬化以后形成的人造石材。混凝土的强度和耐久性,在很大程度上决定于混凝土混合物的一系列性质。通过分析混凝土混合物的性质,简单总结影响混凝土混和物性能的几种因素。 Concrete is a cementitious material with cement as the main material, fly ash and other minerals as excipients, mixed with water, coarse and fine aggregates, and admixtures when necessary, according to a certain proportion, mixed with the mixture, and after coagulation and hardening The formation of artificial stone. The strength and durability of concrete depend largely on the nature of the concrete mixture. By analyzing the nature of the concrete mixture, several factors that affect the properties of the concrete mixture are briefly summarized.
