Full-weight slag aggregate heat-resistant concrete prepared by using ordinary silicate cement
The present invention relates to a fire-resistant material, particularly to a full-weight slag aggregate heat-resistant concrete prepared by using ordinary silicate cement. The full-weight slag aggregate heat-resistant concrete comprises, by weight, 40-80% of a blast furnace heavy slag aggregate, 10-20% of ordinary silicate cement, 10-20% of slag micro-powder, 0-10% of fly ash, and 0-10% of silica micro-powder, wherein 0.01-0.03% of sodium tripolyphosphate and 0.01-0.03% of sodium metaphosphate are added to the raw materials. According to the present invention, the metallurgical solid waste blast furnace heavy slag is adopted to replace the fire-resistant material to prepare the fire-resistant aggregate, the cementitious material adopts the metallurgical solid waste materials such as the slag powder and the fly ash, and the binding agent uses the ordinary silicate cement with no high temperature resistance, such that the existing metallurgical slag resources are completely utilized to form the silicate and aluminate high temperature resistance hydrate during the cement hydration process so as to reduce the generation of the hydroxide unstable substance, enrich the source of the heat-resistant concrete raw materials, and reduce the cost of the heat-resistant concrete.
