摘要
介绍了偏高岭石结构、火山灰性及其在高性能混凝土中应用研究现状。有关研究结果表明:偏高岭土可有效提高水泥砂浆和混凝土的强度,改善混凝土的抗渗性和耐蚀性,有效地抑制碱集料反应等,是一种很有开发应用价值的混凝土功能性掺合料。
The study on the structure, pozzolanic activity and the application in high performance concrete of metakaolin is reviewed. Literatures show that metakaolin has the characteristics of efficiently enhancing the strength of cement mortar and concrete, improving the impermeability and anti-corrosion property of concrete and decreasing the expansion caused by the alkali-aggregate reaction in concrete. It is a kind of promising functional admixture material used for high performance concrete.
