Analysis on the Design of Construction Mix Ratio for Heat-Resistant Concrete

Combined with the heat-resistant concrete used for the construction of a company’s roaster, on the basis of preliminary preferred components for the concrete, with the design theory of ordinary concrete mix ratio, the design study of the mix ratio for C20 ~ C35 heat-resistant concrete was carried out. The study results showed that, the strength of the heat-resistant concrete formulated by the design theory of ordinary concrete mix ratio could meet the requirements, but the strength and water-cement ratio could not satisfy the linear equation. The study provided theoretical reference for the design of mix ratio for heat-resistant concrete.
