Preparation method of high-temperature-resistant concrete material capable of effectively resisting fire damage as well as product and application of high-temperature-resistant concrete material

The invention discloses a preparation method and product application of a high-temperature-resistant concrete material capable of effectively resisting fire damage, oxidized steel slag is acidized to serve as coarse aggregate, waste glass fine aggregate is treated by polystyrene to partially replace river sand fine aggregate, all the components are mixed in proportion, and a novel air entraining agent is doped to prepare high-temperature-resistant concrete. Compared with the traditional high-temperature-resistant concrete, the high-temperature-resistant concrete has the advantages of lower initial slump fluidity and slump fluidity retentivity, higher gas content, higher mechanical property, higher hardening density, higher water absorption rate and lower alkali-silicic acid reaction expansion value. The use of the novel air entraining agent and the high-temperature melting of polystyrene improve the anti-bursting ability and mechanical property residual rate of the concrete, and reduce the generation and deve
