Household garbage incinerator slag alkali slag aerated concrete block and preparation method thereof
The invention provides a household garbage incinerator slag alkali slag aerated concrete block and a preparation method thereof. The granular furnace slag replaces part of river sand; the powdery slagreplaces part of mineral slag in alkali-activated cement; the aerated concrete block comprises dry materials of the composition in percentage by mass: 15-25% of alkali-activated cement doped with powdery furnace slag, 5-15% of lime, 37.0-43.2% of finely ground river sand, 10-15% of waste materials, 2-5% of gypsum, and 8-28% of the granular furnace slag, wherein the sum of the mass percentages ofthe components is 100%, the aluminum powder accounts for 0.07-0.10% of the total mass of the dry materials, and the mass ratio of hot water (at the temperature of 50+/-2 DEG C) to the dry materials is0.45-0.55. The household garbage incinerator slag alkali slag aerated concrete block has the characteristics of high strength, low dry density, high yield and the like, not only can reduce the exploitation of river sand, but also can consume the river sand, so that the household garbage incinerator slag alkali slag aerated concrete block has good economic, social and environment-friendly benefits, and is suitable for large-scale popularization and application.
本发明提供了一种生活垃圾焚烧炉渣碱矿渣加气混凝土砌块及制备方法，其中颗粒状炉渣替代部分河砂，粉状炉渣替代碱激发水泥中的部分矿渣，其组成成分干料以质量百分比计：掺粉状炉渣的碱激发水泥15～25%、石灰5～15%、磨细河砂37.0～43.2%、废料10～15%，石膏2～5%，颗粒状炉渣8～28%，各组分质量百分数之和为100%，铝粉为干料总质量的0.07～0.10%，热水（温度50±2℃）和干料的质量比为0.45～0.55。该生活垃圾焚烧炉渣碱矿渣加气混凝土砌块具有强度高、干密度低、成品率高等特点，不仅可以减少河砂的开采，亦可以将其消耗，因此具有良好的经济、社会和环保效益，适合大规模推广应用。
