Use of Supplementary Cementitious Materials to Manufacture High Performance Concrete

Yan PeiyuDepartment of Civil Engineering, Tsinghua University, Beijing, China

Abstract:Supplementary cementitious materials (SCMs) are very valuable and indispensable for the manufacture of high performance concrete. Use of SCM is necessary for the recycle of solid waste and to produce green and sustainable concrete. The using situation of CSMs in China is shortly reviewed. Fly ash and ground granule blast furnace slag are the most important mineral admixture in Chinese cement and concrete industry. Silica fume is used only for high strength concrete. New kinds of mineral admixture from metallurgical slag is now explored. 20%-40% of binder is SCM in ready-mix concrete for both normal and high strength classes. Even higher dosage of SCM is used to prepare massive concrete or the concrete with high durability. The properties of complex binder containing different kinds and different dosage of mineral admixture are evaluated. Some examples are given to show the performance of high volume mineral admixture concrete and how to use it in the building construction.

Key words: Supplementary cementitious material; high performance concrete; high volume mineral admixture concrete; fly ash; ground granule blast furnace slag
