The invention discloses a method for preparing high-strength lightweight LC50 concrete by using reclaimed sand, which comprises the following preparation steps: acquiring reclaimed sand powder, and preparing the reclaimed sand powder into the reclaimed sand and an early-strength gelling component by means of lamination, impurity removal, mixed grinding and powder selection; the preparation method comprises the following steps: according to a raw material ratio of cement to pottery sand to reclaimed sand to ceramsite of 390: 200: 100: 260, obtaining raw materials, and adding the raw materials into stirring equipment for premixing and stirring to obtain a mixture; the preparation method comprises the following steps: pre-mixing water and a water reducing agent according to a raw material ratio of 150: 5, then adding the mixture into the mixture, continuously stirring to obtain the high-strength light-weight LC50 concrete, and putting the high-strength light-weight LC50 concrete into a mold for molding. The reclaimed sand and the early strength gelling component are adopted to replace pottery sand, full-component efficient utilization of reclaimed sand powder solid waste resources is achieved, consumption of natural resources such as natural sand is reduced, the production efficiency of prefabricated parts is improved, production energy consumption is reduced, and the production cost is saved.
本发明公开了一种利用再生砂制备高强轻质LC50混凝土的方法，包括如下制备步骤：获取再生砂粉，并通过层压、去杂、混磨和选粉的方式将再生砂粉制备成再生砂和早强胶凝组分；按照原料配比，水泥：陶砂：再生砂：陶粒=390:200:100：260，获取原料，并将原料添加到搅拌设备中进行预混合搅拌，获得混合物；按照原料配比，水：减水剂=150:5预混合，再加入所述混合物中，并持续进行搅拌，获得高强轻质LC50混凝土，并将所述高强轻质LC50混凝土放入模具中成型。该发明采用再生砂和所述早强胶凝组分替换陶砂，实现了所述再生砂粉固废资源的全组分高效利用，减少了天然砂等自然资源的消耗，有利于提高预制构件的生产效率，降低生产能耗，节约生产成本。
