Options for Improving the Workability of High Performance Concrete

Article Preview

Abstract:

A low water-cement ratio is one of the main characteristics of high performance concrete thanks to high strength of concrete is achieved. However, it leads to deterioration of the rheological properties and therefore it is necessary to use a plasticizing admixtures. Other options to influence workability are introduced in this article. There is studied the correct selection of cement, the temperature of water, the particle size distribution of aggregates (packing density) and the use of ground granulated blast furnace slag (GGBS). The performed experiments show a greater or lesser influence all studied options on the workability. Therefore this options is appropriate to keep in mind during mix design of high performance concrete.
