Abstract

The invention belongs to the technical field of building material: cement, in particular to slag environment-friendly energy-saving cement. The invention is prepared by the following raw materials inparts by weight: 60-80 parts of limestone, 3-15 parts of anthracite, 3-15 parts of plaster, 5-15 parts of slag and 1-5 parts of additive. The invention makes full use of industrial slag to serve as main raw materials for producing cement, which can not only reuse waste materials, reduce environment pollution, turn waste into treasure, but also reduce production cost of cement. The cement in the invention is characterized by fine weather resistance, durability and abrasive resistance, and the cement prepared by using industrial slag has fine quality, high strength, high grade and low product cost. The invention has broad market applicability, is suitable for development and application in mass, and has remarkable market benefit and social benefit.

Description

technical field

[0001] The invention belongs to the technical field of cement, a building material, and in particular relates to a slag environmental-friendly and energy-saving cement. Background technique

[0002] All kinds of building cements used in the market are cements prepared by conventional methods. This conventionally used cement is generally made by mixing materials such as slag, clay, gypsum, limestone, and iron powder. However, due to the excessive demand for slag, the supply was in short supply, so the cement industry once stagnated. In recent years, in order to save the existing resources of the land, people have begun to make full use of various industrial and agricultural wastes, industrial waste residues and other environmentally friendly materials to manufacture various building materials. How to find a kind of raw material that can replace slag to carry out mass production of cement like this is also one of the technical problems that technical personnel...
