摘要
高性能混凝土具有高工作性、高体积稳定性和高耐久性等优异性能,被称为"21世纪混凝土"。掺入活性矿物掺合料和化学外加剂等组分,可以配制出满足工程施工要求的高性能混凝土,且矿物掺和料替代部分水泥可以减少水泥用量,降低CO2排放量,缓解环境恶化。总结了高性能混凝土中矿物掺合料和化学外加剂的研究进展,介绍了国内外高性能混凝土的配合比设计方法的应用,并对高性能混凝土的现状和发展趋势进行了讨论。
High performance concrete,with high workability,high volume stability,high durability and other excellent properties,is known as“Twenty-first Century Concrete”.High performance concrete that meets the requirement of the construction could be produced through the incorporation of mineral admixture and chemical admixture components.And mineral admixtures replace part of cement can reduce the dosage of cement,then reduce CO 2 emissions and alleviate the deterioration of the environment.This paper summarized the research progress of mineral admixture and chemical admixture in high performance concrete,introduced application of mix proportion design method at home and abroad,then the current situation and development trend of high performance concrete were discussed.
