Abstract

The invention discloses a manufacturing method of a chemical-erosion-resistant cement brick. The manufacturing method comprises the following step: adding 85 parts by weight of flyash, 15 parts by weight of lime and 2 parts by weight of sand into 15 parts by weight of a liquid activating agent to obtain a novel high-strength building material. By the cement brick, discharge pollution of the flyash is reduced, and the cement brick has quite high stability, durability and chemical erosion property, and is high in strength.

Description

technical field [0001] The invention belongs to the technical field of buildings, and in particular relates to a method for making chemically resistant cement bricks. Background technique [0002] Now, with the rapid development of the national economy and the great investment in infrastructure construction, fly ash can be mixed with cement at present, but the early strength of the mixed cement produced is low and the addition amount is generally small, otherwise the strength of the product cannot meet the national standard requirements. Therefore, the utilization rate of fly ash has been very low. Contents of the invention [0003] The object of the present invention is to provide a method for making chemically resistant cement bricks, which solves the problem of the utilization rate of fly ash. [0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a method for making chemically resistant cement bricks...
