Mineralized non-autoclaved aerated building block and preparation process thereof
The invention relates to a mineralized non-autoclaved aerated building block with negative carbon sand, which can recover a large amount of steel slag difficult to treat, has low heat conductivity coefficient, early strength, low cost, no shrinkage and no high temperature, and is composed of a building block core material and a building block outer layer, the building block core material comprises the following components in percentage by weight: 20.0-28.0% of quick lime, 3.0% of gypsum, 10.0-18.0% of 525 cement, and 55.0-67.0% of steel slag powder; the building block outer layer is prepared from the following components in percentage by weight: 20.0 to 28.0 percent of quick lime, 3.0 percent of gypsum, 10.0 to 18.0 percent of 525 cement and 60.0 percent of steel slag powder. The sandwich aerated building block with a light core material and a heavier outer layer is prepared through a two-step pouring and carbon dioxide mineralization method, and the mineralized aerated building block can reach a non-shrinkage state, has early strength and high production efficiency, and is a negative carbon material; and the finally obtained aerated building block is in a medium-heat-preservation form, is very low in heat conductivity coefficient, and is light and high in strength.
本发明涉及一种能大量回收难处理钢渣、导热系数低、早强、低成本、无收缩、免高温、负碳砂的矿化免蒸压加气砌块，由砌块芯材和砌块外层组成，砌块芯材包括以下重量百分比的成分：生石灰20.0～28.0％、石膏3.0％、525水泥10.0～18.0％、钢渣粉55.0～67.0％；砌块外层包括以下重量份的成分：生石灰20.0～28.0％、石膏3.0％、525水泥10.0～18.0％、钢渣粉60.0％。通过2步浇筑和二氧化碳矿化方法，制得芯材轻外层稍重的夹芯加气砌块，矿化加气砌块可达到无收缩状态，早强，生产效率高，且为负碳材料；最终得到的加气砌块为中保温形式，导热系数很低，同时轻质高强。
