混凝土也称砼,是当代最主要的土木工程材料之一。它是由胶结材料,骨料和水按一定比例配制,经搅拌捣成形,在一定条件下养护而成的人造石料。混凝土具有原料丰富,价格低廉,生产工艺简单的优点。同时混凝土还具有投放扩压强度高,耐久性好,强度等级范围,所以混凝土在建筑方面使用十分广泛;文章就从大体积混凝土结构在施工及养护期间温度开裂的机理入手,结合某高校结构试验室加载地沟及反力墙工程大体积混凝土配比实例,探讨了用普通水泥制备高强度等级大体积混凝土的配比设计。
Concrete, also known as concrete, is one of the most important contemporary civil engineering materials. It is a man-made stone material that has been prepared by cementing materials, aggregates and water in a certain proportion, being shaped by stirring, and being preserved under certain conditions. Concrete has the advantages of rich raw materials, low price, and simple production process. At the same time, concrete also has high compression strength, durability, strength range, so the concrete is widely used in construction; the article starts with the mechanism of temperature cracking during construction and maintenance of mass concrete structure, combined with a structural test of a university The proportioning design of large-scale concrete for the loading of trenches and counter-force wall engineering was investigated. The proportioning design of high-strength-grade mass concrete prepared with ordinary cement was discussed.
