Abstract

The invention provides a lightweight ceramisite concrete external wallboard and a preparation method thereof. The external wallboard is characterized by comprising the following components in percentage by weight: 58-75% of ceramisite, 13-21% of cement, 11-21% of medium sand, 0.13-0.92% of waterproof agents, 0.098-0.69% of water reducing agents and 0.065-1.15% of anti-freezing agents. The lightweight ceramisite concrete external wallboard solves the problem that the aerated cement bricks, slag and coal ash bricks, coal ash, stone and cement bricks, which are widely used in the non-bearing external walls in the buildings at present, feature high water absorption, easy cracking and dropping of plastering ceramic tiles and stones, low whole structure strength, low anti-impact and anti-kink load and the like, and is suitable for being used in the buildings.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a lightweight concrete exterior wall panel using ceramsite as an aggregate. Background technique [0002] At present, the non-load-bearing exterior walls widely used in construction mainly include steam-filled cement bricks, slag fly ash bricks, and fly ash gravel cement bricks. Gas-filled cement bricks have a high water absorption rate, and the pasted tiles and stones are easy to crack and fall off, and cannot be nailed, drilled, or threaded horizontally and vertically; slag fly ash bricks and fly ash gravel cement bricks have high water absorption rates, are easy to crack, and have low overall structural strength , impact resistance, low bending load. Contents of the invention [0003] In order to solve the problems of high water absorption, easy cracking, easy deformation, low impact resistance and bending load, and narrow application range of non-load-bearing exterior wal...
