Abstract

A light-weight concrete exterior wall panel is disclosed. The panel is characterized in that components of the panel include coarse ceramsite (with Phi being 0.5-1.0 cm), middle-size ceramsite (with Phi being 0.3-0.5 cm), ceramsite powder (with Phi being 0.3 cm or below), cement, a waterproof agent, a water reducer and an antifreezing agent; and the components include 34.5-43% of the coarse ceramsite (with Phi being 0.5-1.0 cm), 6.9-17.2% of the middle-size ceramsite (with Phi being 0.3-0.5 cm), 13.8-25.8% of the ceramsite powder (with Phi being 0.3 cm or below), 13-21% of the cement, 0.13-0.92% of the waterproof agent, 0.098-0.69% of the water reducer and 0.065-1.15% of the antifreezing agent. The panel overcomes a problem that aerated cement bricks, slag-fly ash bricks, fly ash-broken stone-cement bricks, and the like which are widely used in nonbearing exterior walls of buildings at present have disadvantages of high water absorption rates, liable cracking and shedding of adhered tiles and stone materials, low overall structural intensity, low shock resistance, low flexural load, and the like, and is suitable for application in 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 and ceramsite powder as an auxiliary material. Background technique [0002] At present, the non-load-bearing exterior wall materials widely used in construction mainly include steamed cement bricks, slag fly ash bricks, fly ash gravel cement bricks, etc. 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 , low impact resistance and 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, low bending load, an...
