Description

The autoclaved brick that one kind of multiple mineral are composite

Technical field

The present invention relates to autoclaved brick field, is exactly the composite autoclaved bricks of one kind of multiple mineral.

Background technology

Autoclaved brick is also known as non-burning brick, and its characteristic is that other any wall body brick does not have, and uses rational scientific formula, add peptizer and chemical additives according to a certain percentage, make the rational apparatus and process intensive treatment of granularity, humidity, degree of mixing, reach best plastic state, by high pressure compression moulding, make brick body rapid curing, time is longer, and effect is better, and the practicality of brick is good, need not soak when building a wall, outward appearance is neat.Due to this kind, the strength of materials is high, good endurance, dimensional standard, profile are complete, color and luster is homogeneous, has the outward appearance of primitive simplicity and nature, can do dry wall and also can do any external decoration.Therefore, be a kind of extremely promising renewal product replacing clay brick.

Existing autoclaved brick due to consistency before individual material bad, therefore easy embrittlement, insufficient strength is long, and work-ing life falls short of, simultaneously inadequate environmental protection.
