Silicate cement prepared from solid wastes and preparation method of silicate cement
The invention discloses silicate cement prepared from solid wastes and a preparation method of the silicate cement and belongs to the technical field of building materials. The silicate cement is prepared from the raw materials: clinkers, gypsum, slag, tailings and building wastes by adding a chemical excitant. The silicate cement is prepared from the following raw materials in percentage by weight: 40-60% of clinkers, 5-12% of gypsum, 8-15% of slag, 10-25% of tailings and 20-45% of building wastes, wherein the use level of the chemical excitant is 0.02-0.08% of the total weight of the raw materials; the slag is slag without metallic iron; the tailings are wastes left by exploiting a mine; the building wastes are building waste bricks or concrete plate blocks without metals or other impurities. The silicate cement disclosed by the invention is widely applied to concrete and cement products, relieves increasingly deficient clinker firing resources and reduces discharge of carbon dioxide of cement, thereby facilitating reduction of severe haze in atmosphere. primary resources are saved and replaced, so that the circular economy development is promoted and the pollution is reduced to protect the ecological environment. In the production process, further pollution on the environment is not generated.
