Sound absorption type foam concrete plate prepared from tailing sand and preparation method of sound absorption type foam concrete plate
The invention discloses a sound absorption type foam concrete plate using tailing sand and a preparation method thereof. The preparation method comprises the following steps: uniformly stirring a cementing material, an admixture and a regulator; adding water and an additive, and stirring into slurry in a uniform flow state; adding the tailing sand into the slurry, and uniformly mixing and stirring; adding a foaming agent into the stirred slurry, and uniformly stirring; injecting the stirred mixture into a mold, standing and curing, and demolding; and cutting off cement paste on the surface of a product obtained by demolding by using a cutting machine to expose micropores, so that the board has a sound absorption function. The mixture is prepared from the following substances in percentage by weight: a cementing material, tailing sand, an admixture, a regulator, an additive, water, a foaming agent and a waterproof agent. The foam concrete plate is high in strength, small in shrinkage rate and high in permeability, integrates heat preservation, sound absorption and fire prevention, and is easy and convenient to produce and manufacture.
本发明公开了一种利用尾矿砂的吸声型泡沫混凝土板及其制备方法，包括如下步骤：将胶凝材料、掺合料及调节剂搅拌均匀；加入水、外加剂搅拌成均匀流态的料浆；将尾矿砂加入料浆中混合搅拌均匀；将发泡剂加入搅拌好的料浆中搅拌均匀；将搅拌好的拌合物注入模具内，静置养护、脱模；将脱模得到的产品使用切割机将表面的水泥浆切除表面露出微孔使得板材具有吸声功能。所述拌合物由以下重量百分比的物质组成：胶凝材料、尾矿砂、掺合料、调节剂、外加剂、水、发泡剂、防水剂。本发明的泡沫混凝土板强度高、收缩率小、渗透性高，集保温、吸声、防火于一体，生产制造简便。
