Cement autoclaved brick and production method thereof

Abstract

The invention discloses a cement autoclaved brick and a production method thereof and belongs to the field of a wall material. The cement autoclaved brick is prepared from cement, sand, blast-furnace slag, coal ash and water. According to the invention, the cement is mainly used as a calcium material and the cement has fast hardening property, sulfate resistance, hydrothermal expansion property and high temperature resistance. Compared with the use of standard lime autoclaved brick, the lime has the defects of high hydration heat in hydration process, slow hardening, low strength after hardening and poor water durability, but the freezing resistance, corrosion resistance, compressive strength, and the like, of the cement autoclaved brick are better than those of the traditional brick. According to the invention, the blast-furnace slag is used as a production raw material, so that the problems difficult to be solved of the blast-furnace slag in mining industry can be effectively solved, and meanwhile, the production cost of the enterprise can be reduced.

Description

technical field [0001] The invention relates to the field of wall materials, in particular to a cement autoclaved brick and a production method thereof. Background technique [0002] Brick is a kind of building material, and its appearance is in the shape of small rectangular parallelepiped. It is the main material for forming walls. At present, the bricks produced are mainly clay bricks. The production process needs to consume arable land and a lot of energy. It consumes more than 1 billion cubic meters of clay resources and more than 70 million tons of standard coal every year. How to reduce energy consumption and produce a clay brick with characteristics The bricks to meet construction needs became a big problem that needed to be solved urgently. Contents of the invention [0003] 1. The technical problem to be solved by the invention [0004] Aiming at the defects and deficiencies in the prior art, the present invention provides a cement autoclaved brick and its prod...
