小议桥梁工程中水泥混凝土技术性能及其应用

Technical Performance of Cement Concrete and Its Application in the Bridge Project

在桥梁工程中应用最广泛的是普通混凝土:以水泥为胶凝材料,以砂,石为骨料,加水拌制成的水泥混凝土.普通混凝土normal concrete一般指以水泥为主要胶凝材料,与水、砂、石子,必要时掺入化学外加剂和矿物掺合料,按适当比例配合,经过均匀搅拌、密实成型及养护硬化而成的人造石材。因此,水泥混凝土技术性能控制对工程质量保证至关重要。

What is the most widely used in bridge engineering is the normal concrete which takes the cement as the cementitious material,the sand and stone as the aggregate,and then add water to mix.Normal concrete is generally refers to the artificial stone with cement which is the main cementitious material,water,sand and gravel,including chemical admixtures and mineral admixtures if necessary,with an appropriate proportion,uniform mixing,forming dense and conservation rigidification.Therefore,the technical performance control of cement concrete is essential to project quality assurance.
