The invention provides preparation and application of stone chip concrete, which is prepared from the following raw materials in parts by weight: 200 parts of Portland cement, 175 parts of limestone stone chips, 260 parts of broken stone, 75 parts of slag powder, 13 parts of surfactant, 9 parts of polytetrafluoroethylene fiber, 10 parts of water reducing agent and 150 parts of water. As the price of the stone chips is lower than that of the sandstone, the cost of the material is reduced, and the material has better weather resistance and bending resistance. The invention introduces application of stone chip concrete in preparation of cement prefabricated parts, and realizes energy conservation and emission reduction in the concrete industry on the premise of ensuring that the concrete performance meets the design and construction requirements.
本发明提供一种石屑混凝土的制备及应用，包括以下重量份的原料：硅酸盐水泥200份、石灰岩石屑175份、碎石260份、矿渣粉75份、表面活性剂13份、聚四氟乙烯纤维9份、减水剂10份、水150份，它用石屑代替了部分砂石，解决了天然砂短缺问题，由于石屑价格较之砂石价格低，降低了材料的成本，具有较好的耐气候性和抗挠曲性。本申请介绍了石屑混凝土于制备水泥预制件中的应用，在保证混凝土性能满足设计和施工要求的前提下，对实现混凝土行业的节能减排。
