Method for preparing aggregate and concrete from industrial solid wastes
The invention discloses a method for preparing aggregate from industrial solid waste. The method comprises the following preparation steps of S1, mixing the industrial solid waste and an excitant, anduniformly stirring, and S2, conducting extrusion molding and drying, and acquiring aggregate. The aggregate prepared by the method can be used for preparing concrete. The method comprises the following steps of S1, stacking the dried aggregate in a mold, S2, pouring high-flow-state slurry, and S3, after the strength is achieved, conducting demolding to obtain a concrete product. According to themethod, the aggregate is prepared by directly mixing the industrial solid waste with the excitation material, secondary processing treatment on solid waste materials is not needed, the method is suitable for large-scale industrial production, concrete can be conveniently prepared on site or concrete products can be conveniently manufactured in factories by pouring high-flow-state slurry through pre-filled aggregate, and the surface can also be further protected. Therefore, the requirement for large-scale low-cost treatment of industrial solid waste can be met, secondary pollution is remarkablyreduced, and a complete original-state industrial solid waste treatment system is formed.
本发明公开了一种利用工业固体废弃物制备骨料的方法，包括如下制备步骤：S1、将工业固体废弃物、激发剂混合，搅拌均匀；S2、挤出成型、干燥，得到骨料。上述方法制备得到的骨料，可制备混凝土：S1、将干燥后的骨料堆放在模具中；S2、浇注高流态浆料；S3、达到强度后脱模，即得到混凝土产品。上述方法采用工业固体废弃物直接与激发材料混合来制备骨料，无需对固废材料进行二次加工处理，适于大规模工业化生产，采用预填骨料浇注高流态浆液可以方便地现场制备混凝土或工厂制作混凝土制品，表面也可以进一步进行防护处理。从而，可以满足大规模低成本处理工业固体废弃物的需求，显著减少二次污染，形成完整的原状工业固体废弃物处理体系。
