Low-alkali compression-resistant fracture-resistant environment-friendly concrete and preparation method thereof
The invention relates to the technical field of environment-friendly concrete, and discloses low-alkali compression-resistant fracture-resistant environment-friendly concrete and a preparation method thereof. The low-alkali compression-resistant fracture-resistant environment-friendly concrete is prepared from the following raw materials in parts by weight: 6 parts of cement, 0.1 part of ground slag, 8 parts of sand, 15 parts of stones, 1 part of water, 1 part of a reinforcing agent, 0.2 part of a fiber material and 1 part of dolomite powder. In a preferred embodiment, the dosage of the ground slag is controlled to be 20-50% of the content of the cement, and the mesh number of the ground slag is 350m<2>/kg or above. In a preferable implementation mode, the reinforcing agent comprises a water reducing agent, an air entraining agent, a retarder, a waterproof agent, an expanding agent and an anti-freezing agent. The cement, the ground slag, the sand, the stones and the water are arranged, and the reinforcing agent, the fiber material and the dolomite powder are added, so that the produced concrete has the advantages of alkali resistance, good stability, high strength, high durability, high resistance to pressure and good fracture resistance.
本发明涉及绿色环保混凝土技术领域，且公开了一种低碱抗压抗折绿色环保混凝土及其制备方法，所述低碱抗压抗折绿色环保混凝土采用以下重量份的原料制得：水泥6份、磨细矿渣0.1份、砂子8份、石子15份、水1份、加入增强剂1份、纤维材料0.2份、白云石粉1份，在一个优选地实施方式中，所述磨细矿渣的掺量控制在水泥含量的20％～50％之间，所述磨细矿渣的目数为表面积350m2/kg以上，在一个优选地实施方式中，所述增强剂包含：减水剂、引气剂、缓凝剂、防水剂、膨胀剂、防冻剂，通过设有水泥、磨细矿渣、砂子、石子、水、加入增强剂、纤维材料、白云石粉，有利于使生产出来的混凝土，具有耐碱性，稳定性良好、强度高、耐久性好、高抗压、抗折性能好。
