矿物掺和料对高性能混凝土性能的影响

通过对6组具有代表性的不同配合比混凝土拌和物和试块的性能测试，研究了高性能混凝土在掺入不同比例的粉煤灰、矿粉后的物理、力学性能、耐久性能以及经济性。结果表明：掺入粉煤灰、矿粉对混凝土的性能有明显的改善作用，复合掺入比不掺或单掺矿物掺料具有更好的效果，保证了施工质量。

Effect of Mineral Admixture on Performance of High Performance Concrete

Through testing the properties of concrete mixture and concrete test cubes which had six kinds of mix proportion, the physical property, mechanical property, durability and economy of high performance concrete which added different proportions of fly ash and slag fume were studied. The results indicate that fly ash and slag fume can improve the properties of concrete obviously. It can obtain better effects if adding two kinds of minerals into the concrete at the same time, and can ensure the construction quality.
