Abstract

The invention discloses an environmental-friendly cement tile mixed with ballast and a preparation method thereof. The environmental-friendly cement tile is prepared by adding ballast on the basis of a common cement tile raw material and comprises the following raw materials: 5-150 parts of ballast, 80-130 parts of cement, 0-165 parts of sand and 20-39 parts of water. Tests prove that the ballast added into the cement tile not only improves the breaking strength of the cement tile, but also can consume fine chips and stone chips generated in the process of mechanically processing broken stone in a plurality of waste quarries; 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 ballast and a preparation method thereof. Background technique [0002] In our country, there are abundant mineral resources, and the rich mineral resources have driven the development of the stone industry. These enterprises have produced a large amount of waste stone ballast and waste stone powder during processing. With the rapid development of the stone industry, the total amount of waste rock ballast and waste rock powder has increased year by year. As waste accumulations in stone quarries, they not only occupy the site but also pollute the environment. Thereby the disposal of waste rock ballast and waste rock powder has become a serious social problem. [0003] Cement tiles (also known as concrete tiles) have a long history. This industry is one of the most traditional, low...
