Abstract

The invention discloses an environmental-friendly cement tile mixed with biological power plant residual dust and a preparation method thereof. The environmental-friendly cement tile is prepared by adding biological power plant residual dust on the basis of a common cement tile raw material and comprises the following raw materials: 5-40 parts of biological power plant residual dust, 50-125 parts of cement, 120-170 parts of sand, 0-2.0 parts of water repellent and 20-39 parts of water. Tests prove that the residual dust added into the cement tile leads the breaking strength of the cement tile to meet the standard requirement and can consume dust removal residues of a plurality of waste heat power plants; 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 residual ash from a biological power plant and a preparation method thereof. Background technique [0002] In my country, thermal power plants are widely distributed, making the residual ash of power plants spread all over the country, and the distribution is extremely wide. In recent years, my country's energy industry has developed steadily, with an annual growth rate of 7.3% in power generation capacity. Power plant ash has become one of the largest industrial wastes in my country. The rapid development of the electric power industry makes the total amount of power plant ash increase year by year. The power plant ash not only pollutes the environment, but also wastes resources. Therefore, the treatment of power plant ash has become a serious social problem. [0003] Cement til...
