Problems solved by technology

[0004] The traditional cement manufacturing process uses silicate as a raw material for preparation, and the raw material selection has problems such as waste of resources and environmental pollution. Moreover, with the acceleration of urbanization, the demand for cement in social development is increasing, and more and more It increases the consumption of cement manufacturing and increases the burden of cement production. Therefore, we propose an environmentally friendly cement

Abstract

The invention discloses an environment-friendly cement and a preparation method thereof. The environment-friendly cement consists of ordinary Portland cement, white cement, limestone, slag, aluminum chloride, industrial waste residue, fly ash residue, kaolin, calcium carbonate, plastic fiber, river sand, iron powder and iron ore, and the components in parts by weight are: 20-28 parts of the ordinary Portland cement; 2-6 parts of the white cement; 30-40 parts of the limestone; 10-18 parts of the slag and 10-20 parts of the aluminum chloride. According to the invention, waste materials such as the slag, the industrial waste residue, the fly ash residue, the plastic fiber and the like are added in a large amount to the raw materials, so that the recycling rate of solid wastes such as industrial waste, construction waste and the like is effectively improved, the damage to the environment is reduced, and the aims of green energy conservation, environmental protection, comprehensive utilization of resources and development of circular economy strongly advocated by the state are achieved; meanwhile, the preparation method is simple, no additional process is needed, the market competitiveness of the environment-friendly cement is guaranteed, and the self-interest of enterprises is met.

Description

technical field [0001] The invention relates to the technical field of cement, in particular to an environmentally friendly cement and a preparation method thereof. Background technique [0002] Cement is a powdery hydraulic inorganic gelling material. It can be mixed with water to form a slurry. It can be hardened in the air or better hardened in water, and can firmly bind sand, stone and other materials together. Early lime and volcanic ash The mixture is very similar to the modern lime pozzolanic cement. The concrete made of crushed stone is cemented with it. After hardening, it not only has high strength, but also can resist the erosion of fresh water or salt water. It has been used as an important cementing material for a long time. , Widely used in civil engineering, water conservancy, national defense and other projects. [0003] According to the purpose and performance of cement, it is divided into: general-purpose cement, cement commonly used in general civil const...
