摘要：
随着我国改革开放，大规模的经济建设开展，建筑群体发展十分迅速,而混凝土是土木工程中用途最广、用量最大的一种建筑材料。混凝土的历史可以追溯到古老的年代。其所用的胶凝材料为粘土、石灰、石膏、火山灰等。20世纪初，有人发表了水灰比等学说，初步奠定了混凝土强度的理论基础。以后，相继出现了轻集料混凝土、加气混凝土及其他混凝土，各种混凝土外加剂也开始使用。60年代以来，广泛应用减水剂，并出现了高效减水剂和相应的流态混凝土；高分子材料进入混凝土材料领域，出现了聚合物混凝土；多种纤维被用于分散配筋的纤维混凝土。现代测试技术也越来越多地应用于混凝土材料科学的研究。
混凝土是由胶结材料骨料和水按一定比例配制，经搅拌振捣成型，在一定条件下养护而成的人造石材。混凝土具有原料丰富，价格低廉，生产工艺简单的特点，因而使其用量越来越大；同时混凝土还具有抗压强度高，耐久性好，强度等级范围宽，使其使用范围出十分广泛，不仅在各种土木工程中使用，就是造船业，机械工业，海洋的开发，地热工程等，混凝土也是重要的材料。
混凝土结构在建筑工程中占有很大的比重，在结构的安全、可靠度和耐久性方面起绝对的作用。因此，对混凝土的质量控制至关重要。本文对混凝土的质量控制进行了详细的阐述。
