Molding sand-based high-activity slurry and low-density autoclaved sand aerated concrete prepared from same
The invention discloses molding sand-based high-activity slurry. Raw materials of the molding sand-based high-activity slurry comprise a water-cooled calcined material and water, wherein the water-cooled calcined material is obtained by taking molding sand, a limestone material and high-calorific-value solid waste as main raw materials and carrying out mixing, low-temperature calcination and rapid water cooling. The molding sand and the limestone material are used as main raw materials, crystal form transformation of a quartz phase in the molding sand is promoted after mixed calcination, impurities in the molding sand are effectively removed, and part of silicon-calcium minerals are generated; then quenching is carried out, the activity of the molding sand is effectively improved, the partial expansion effect is reserved, meanwhile, the microstructure of the lime is optimized, and the silicon-calcium reaction in the autoclaved curing process is easier to carry out; when being applied to preparation of aerated concrete, the composite material can effectively take strength, heat preservation, drying shrinkage and other properties into consideration, has remarkable environmental and economic benefits, and is suitable for popularization and application.
本发明公开了一种型砂基高活性料浆，其原料包括水冷煅烧料和水；其中水冷煅烧料以型砂、石灰石质材料和高热值固废为主要原料，进行混料、低温煅烧、快速水冷降温得到。本发明以型砂和石灰石质材料为主要原料，经混合煅烧后促进型砂中石英相的晶型转化，有效去除型砂中的杂质，并生成部分硅钙矿物；然后进行急冷，在有效提高型砂活性并保留部分膨胀作用的同时，优化石灰的微观结构，使蒸压养护过程中的硅钙反应更易进行；将其应用于制备加气混凝土，可有效兼顾强度、保温和干燥收缩等性能，具有显著的环境和经济效益，适合推广应用。
