Method for preparing dry-mixed mortar by curing fly ash with waste residues
The invention discloses a method for preparing dry-mixed mortar by curing fly ash with waste residues. The cured fly ash blocky materials discharged by a waste incineration plant are pulverized into cured fly ash products with the granularity capable of passing through a 0.9-micron sieve through a pulverizer, the water content is controlled within 0.5%, 8-14 parts by mass of the cured fly ash blocky materials and 1-3 parts by mass of cement are mixed and stirred to be uniform through a stirrer, and the dry-mixed mortar is obtained; the waste residue solidified fly ash can directly replace natural resource river sand and mine sand mining products by 100% to be used for preparing dry-mixed mortar, and can be widely applied to various constructional engineering construction material mortars for industry, civil use and the like. The dry-mixed mortar disclosed by the invention is low in preparation energy consumption and advanced and simple in process, the strength, the frost resistance, the shrinkage rate, the bonding strength, the water retention rate and the like of the cured fly ash dry-mixed mortar can be obviously improved, and a new solution is provided for a cured fly ash blockymaterial discharged by a waste incineration plant.
本发明公开了一种采用废渣固化飞灰制备干混砂浆的方法，将垃圾焚烧厂排出的固化飞灰块状材料，经粉碎机粉成0.9μm筛能通过的粒度的固化飞灰产品，水分控制在0.5%以内，按质量份计为8‑14份，与水泥按质量份计为1‑3份一起经搅拌机混合搅拌均匀，即得干混砂浆；本发明中的废渣固化飞灰可直接100%替代天然资源河砂、矿山采砂产品用于制备干混砂浆，广泛用于工业及民用等各种建筑工程建设用料砂浆。本发明中的干混砂浆制备能耗低、工艺先进简单，能明显提高固化飞灰干混砂浆的强度、抗冻性能、收缩率、粘结强度、保水率等性能，为垃圾焚烧厂排出的固化飞灰块状材料提供了一条新的解决技术方案。
