Abstract

The invention belongs to the technical field of energy conservation and emission reduction and discloses green and environment-friendly cement. The green and environment-friendly cement is composed of the following raw materials in parts by weight: 5-20 parts of clinker, 3-8 parts of gypsum, 10-20 parts of sorted municipal solid waste incineration bottom ash, 10-20 parts of aluminum profile waste residues, 30-60 parts of smelting slag, 0.1-0.5 part of a reinforcing agent, 0.02-0.05 part of a grinding aid and 0.01-0.1 part of a hexavalent chromium ion reducing agent. According to the green and environment-friendly cement disclosed by the invention, the municipal solid waste incineration bottom ash and the aluminum profile waste residues can be effectively utilized, and the environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of energy saving and emission reduction, and in particular relates to a green environmental protection cement. Background technique [0002] In today's world, every step of the development of human society is almost inseparable from cement. People use cement to build high-rise buildings, pave roads, erect bridges, build subways, etc., and carry out large-scale construction activities of human social infrastructure, which greatly contributes to the development of human society. It improves the living, working and traveling environment of human beings. However, while the use of cement brings great convenience to human beings, it also has a huge negative impact on our ecological environment. The process of producing clinker is the most important part of the cement industry to consume resources and discharge pollutants, so reducing the amount of cement clinker is an important way for the cement industry to save ...
