Selection Research on Materials of Heat-Resistant Concrete Based on Range Theory

Based on the technical performance index of heat-resistant concrete in a project, combined with local material performance and market supply and demand, based on the mix ratio for the concrete of strength C25, five factors as cementitious materials, admixtures, coarse aggregate, fine aggregate, admixtures were selected, every factor selected two levels, by orthogonal experiments, based on range theory, the heat-resistant concrete components that were the most suitable for the project were selected, and provided a research base for further preparation of different strength grade heat-resistant concrete.
