Copper slag concrete block and preparation method thereof
The invention relates to a copper slag concrete block and a preparation method thereof, and belongs to the technical field of environment-friendly aerated concrete blocks. The building block is prepared from the following components in parts by weight: 220 to 270 parts of Portland cement, 160 to 200 parts of gravel, 100 to 150 parts of admixture, 80 to 120 parts of self-compacting particles, 10 to 15 parts of water reducing agent and 8 to 15 parts of foaming agent, according to the invention, the concrete block is filled with the copper ore waste residues in two modes of admixture and self-compacting particles, the doping amount reaches about 15%, the compressive strength of the prepared block reaches 4.27-4.35 MPa, and the density is 595-610 kg/m < 3 >; the self-compacting particles absorb water and expand in concrete to form nearly spherical spaces to modify the hole pattern of air holes, meanwhile, aluminum silicate fibers, cement and other filler are extruded to be solidified to form a high-strength wall shell, when water permeates into the building block, the self-compacting particles absorb water and expand to fill the air holes, and the anti-seepage effect is achieved.
本发明涉及一种铜矿渣混凝土砌块及其制备方法，属于环保型加气混凝土砌块技术领域。该种砌块按照重量份计包括：硅酸盐水泥220‑270份、砂石160‑200份、掺合料100‑150份、自密实颗粒80‑120份、减水剂10‑15份和发气剂8‑15份；本发明将铜矿废渣以掺合料和自密实颗粒两种方式填充在混凝土砌块中，掺加量达到15％左右，制得到砌块抗压强度达到4.27‑4.35MPa，密度为595‑610kg/m3；本发明的自密实颗粒在混凝土中吸水膨胀形成近球状的空间，修饰气孔的孔型，同时挤压硅酸铝纤维与水泥以及其他填料固化后形成高强的壁壳，当水渗入砌块中，自密实颗粒吸水膨胀填充气孔，起到抗渗作用。
