Abstract

The invention discloses an environmental-friendly cement tile mixed with slag and a preparation method thereof. The environmental-friendly cement tile is prepared by adding slag on the basis of a common cement tile raw material and comprises the following raw materials: 5-60 parts of slag, 80-130 parts of cement, 75-165 parts of sand, 0-1.6 parts of water repellent and 20-39 parts of water. Tests prove that the slag added into the cement tile leads the breaking strength of the cement tile to meet the standard requirement and can consume waste residues generated after a plurality of lump coal or pea coal is burnt; and the invention utilizes the waste, saves resources and protects the environment. The invention plays an important role in the field of construction and has wide market prospect.

Description

technical field [0001] The invention relates to the field of building materials, and mainly relates to the reuse of industrial waste, in particular to an environment-friendly cement tile mixed with slag and a preparation method thereof. Background technique [0002] my country is a large coal-producing country. In recent years, my country's energy industry has developed steadily. The loose or lumpy residue after burning lump coal or granular coal that has not been quenched by water has become one of the industrial wastes with a large discharge volume in my country. With a large amount of emissions increasing year by year, these slags have not been recycled, which has caused huge pressure on my country's national economic construction and ecological environment. [0003] Cement tiles (also known as concrete tiles) have a long history. This industry is one of the most traditional, low-investment and widely distributed production industries in China. The usual cement tiles use ...
