前言 高性能混凝土HPC以其诸多的优点得到人们普遍重视,有人称HPC是“21世纪混凝土”。使用优质活性矿物细掺料是配制HPC最重要的技术手段之一,HPC中常用的矿物掺合料有硅灰、优质粉煤灰、优质矿渣等。传统的细掺料有着一定的不足,掺矿渣混凝土必须耗费大量能源超细粉磨矿渣;掺硅灰混凝土虽具有优良的力学性能及耐久性,但硅灰价格昂贵,每吨要2000元左右,且产量有限,美国年产量最大,也仅30万t,中 Preface High performance concrete HPC has been widely valued by people for its advantages. Some people call HPC “concrete in the 21st century”. The use of high quality active mineral fine admixture is one of the most important technical means to formulate HPC. The commonly used mineral admixture in HPC includes silica fume, high-quality fly ash and high-quality slag. The traditional fine admixture has a certain lack of concrete slag mixed with slag must spend a lot of energy superfine grinding slag; although the silica fume concrete with excellent mechanical properties and durability, but expensive silica fume, 2,000 yuan per ton, And limited production, the United States the largest annual output, only 300,000 t, in
