Abstract

The invention provides a lightweight fiber cement tile and a preparation method thereof. The lightweight fiber cement tile is prepared from, by weight, 50-60 parts of yellow sand, 40-45 parts of cement, and 0.3-0.5 part of fibers. The lightweight fiber cement tile has advantages that due to tile thickness reduction, tile weight is reduced without reduction of intrinsic properties such as coveragearea, breaking strength and water absorption of the tile, and accordingly tile preparation cost is saved, and construction and transport cost reduction can be benefited. Therefore, the lightweight fiber cement tile has a profound significance to the construction industry and is a great response to national energy conservation and emission reduction.

Description

technical field [0001] The invention belongs to the technical field of construction industry, and in particular relates to a lightweight fiber cement tile and a preparation method thereof. Background technique [0002] Cement tile is a building material often used in buildings such as warehouses and factories. The existing molded cement tile adopts raw materials composed of cement and yellow sand, and its preparation process is as follows: simply mixing cement and yellow sand. The tiles thus produced have a problem of heavy weight, which is disadvantageous for transportation and construction. Contents of the invention [0003] Aiming at the defects in the prior art, the present invention provides a lightweight fiber cement tile and a preparation method thereof, which can effectively solve the above problems. [0004] The technical scheme that the present invention adopts is as follows: [0005] The invention provides a lightweight fiber cement tile, which comprises the ...
