Environment-friendly solid waste recycled concrete and preparation process thereof
The invention relates to the technical field of building materials, in particular to environment-friendly solid waste recycled concrete and a preparation process thereof. The recycled concrete is prepared from the following raw materials in parts by weight: 150 to 200 parts of Portland cement, 120 to 180 parts of recycled concrete aggregate, 200 to 280 parts of river sand, 40 to 70 parts of clay, 7 to 12 parts of compound basifier, 1.5 to 2 parts of synergistic water reducer, 3 to 6 parts of calcium chloride, 15 to 25 parts of fly ash, 1.5 to 2.8 parts of silane coupling agent, 3 to 7 parts of polypropylene fiber, 1.8 to 3 parts of water reducer, 2 to 6 parts of air entraining agent and 50 to 80 parts of water, the recycled concrete prepared by the invention not only has better mechanical property and durability, but also takes the building waste cement and the building blocks as the raw materials of the concrete aggregate, so that the environmental pollution caused by the building waste cement and the building blocks is effectively relieved, and the purposes of turning waste into wealth and saving the production cost are also achieved.
本发明涉及建筑材料技术领域，具体为一种环保型固废再生混凝土及其制备工艺；所述再生混凝土由以下重量份的原料组成：150～200份硅酸盐水泥、120～180份再生混凝土骨料、200～280份河砂、40～70份黏土、7～12份复配碱化剂、1.5～2份协效减水剂、3～6份氯化钙、15～25份粉煤灰、1.5～2.8份硅烷偶联剂、3～7份聚丙烯纤维、1.8～3份减水剂、2～6份引气剂及50～80份水；本发明制备的再生混凝土不仅具有较好的力学性能及耐久性能，而且其以建筑废弃水泥、砌块作为混凝土骨料的原料，不仅有效地缓解了其对环境的污染，而且也实现了变废为宝，节约生产成本的目的。
