Silicon-based composite reagent reinforced recycled aggregate and preparation method thereof
The invention belongs to the field of aggregate reinforcement, and particularly relates to a silicon-based composite reagent reinforced recycled aggregate and a preparation method thereof. The preparation method comprises the following steps: crushing and screening a primary mortar test block, and washing to remove impurities to obtain low-quality recycled coarse aggregate; then adding lime milk and a surfactant into the low-quality recycled coarse aggregate under a certain condition, stirring, standing, and circularly stirring; adding water, a water repellent agent, silica fume and fly ash, and standing for 6-12 hours; and finally, carrying out immersion cleaning in water to remove soluble impurities on the surface of the recycled aggregate, and air-drying to obtain the silicon-based composite reagent reinforced recycled aggregate. According to the method, industrial by-products such as silica fume and fly ash are comprehensively utilized, the application potential of industrial waste products in the field of building solid waste resource utilization is explored, the resource utilization rate is increased, industrial solid waste is efficiently utilized, and resource preservation and waste recycling are facilitated.
本发明属于骨料强化领域，具体涉及一种硅基复合试剂强化再生骨料及其制备方法。该制备方法包括以下步骤：将原生砂浆试块破碎，筛分后，冲洗去除杂物得到低品质再生粗骨料；后在一定条件下，向低品质再生粗骨料中加入石灰乳和表面活性剂，搅拌后静置，循环搅拌。后加入水、疏水剂、硅灰和粉煤灰，保持静置6～12小时；最后在水中浸洗，去除再生骨料表面可溶杂质，风干后即可得到硅基复合试剂强化再生骨料。该方法通过综合利用硅灰和粉煤灰等工业副产品，发掘了工业废产物在建筑固废资源化利用领域的应用潜力，增加资源利用率，高效利用了工业固废，有利于资源保存和实现废弃物的再利用。
