Colored pervious concrete utilizing industrial waste residues and preparation method
The invention provides colored pervious concrete utilizing industrial waste residues, and relates to the technical field of building materials. The colored pervious concrete is prepared from the following components in parts by weight: 30 to 45 parts of white cement, 0 to 7 parts of phosphorus slag powder, 0 to 1.5 parts of gypsum, 0 to 1 part of lime, 0 to 170 parts of slag stone, 0 to 170 partsof tailings, 0.8 to 1.2 parts of a cementing material, 0.8 to 1.2 parts of a coloring agent and 9 to 13 parts of water. The colored pervious concrete has the advantages and effects that part of cementis replaced by the phosphorus slag powder, and the gypsum and the lime are used as excitants, so that the industrial by-product phosphorus slag powder can be effectively utilized. Secondly, aggregates completely use the slag stone and the tailings, and the slag stone needs to be pre-wetted for 12 hours, so that industrial by-products such as the slag stone and the tailings can be effectively utilized. And thirdly, superfine stone powder is adopted in a cementing agent to replace silica fume, so that the pervious concrete is light in bottom color and easier to color. The prepared colored pervious concrete has good physical and mechanical properties, water-permeable and air-permeable functions and sound-absorbing and noise-reducing functions, is coordinated with the natural environment, andimproves the urban environment.
本发明提供一种利用工业废渣的彩色透水混凝土，涉及建筑材料的技术领域，包括以下成分，以重量份计算：白水泥30～45份、磷渣粉0～7份、石膏0～1.5份、石灰0～1份、矿渣石0～170份、尾矿石0～170份、胶结料0.8～1.2份、着色剂0.8～1.2份、水9～13份。本发明的优点和效果：将磷渣粉替代部分水泥，以石膏、石灰作激发剂，可有效利用工业副产物磷渣粉。其次，骨料完全使用矿渣石、尾矿石，矿渣石需预润湿12h，可有效利用工业副产物矿渣石、尾矿石。再次，在胶结剂中采用超细石粉替代硅灰，保证透水混凝土底色较浅，更容易上色。所制彩色透水混凝土具有良好的物理力学性能、透水透气功能、吸声降噪功能，与自然环境相协调，改善城市环境。
