Abstract

A lightweight concrete exterior wall panel, which is characterized in that its composition is coarse ceramsite (φ0.5‑1.0cm), medium ceramsite (φ0.3‑0.5cm), ceramsite powder (less than φ0.3cm) , cement, waterproofing agent, water-reducing agent, antifreeze; its composition ratio is (by weight) coarse ceramsite (φ0.5‑1.0cm) 34.5‑43%, medium ceramsite (φ0.3‑0.5cm) 6.9‑ 17.2%, ceramsite powder (below φ0.3cm) 13.8‑25.8%, cement 13‑21%, waterproofing agent 0.13‑0.92%, water reducing agent 0.098‑0.69%, antifreeze agent 0.065‑1.15%. It solves the problems of high water absorption rate, easy cracking and falling off of pasted tiles and low overall structural strength of steamed cement bricks, slag fly ash bricks, fly ash gravel cement bricks, etc. Impact resistance, low bending load and other issues, suitable for use in construction.

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 , 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, low bending load, and poor ...
