High-strength porous water permeable brick and preparation method thereof
The invention belongs to the field of building materials, and particularly relates to a high-strength porous water permeable brick and a preparation method thereof. Industrial coal slag is subjected to carbon reduction treatment, and shale is subjected to modification treatment; the content of fixed carbon in coal cinder is reduced, the high-strength porous water permeable brick is prepared through the steps of grinding, aging, pulping, extrusion molding, firing and the like, the compressive strength reaches 31 MPa, the water permeability coefficient reaches 5.01 * 10 <-2 > cm/s, the heat conductivity coefficient reaches 0.65 W/m < 2 >. K, and the volume density is 1350 kg/m < 3 >. The high-strength porous water permeable brick can be used for paving a sponge city road, and can also be used for building a building bearing wall.
本发明属于建筑材料领域，具体涉及一种高强度多孔透水砖及其制备方法；对工业煤渣进行减碳处理、对页岩进行改性处理，降低了煤渣中固定碳的含量，通过研磨、陈化、制浆、挤出成型、烧制等步骤制得一种高强度多孔透水砖，抗压强度达到31MPa，透水系数5.01×10‑2cm/s，导热系数达到0.65W/m2·k，体积密度为1350kg/m3。使其除了可用作海绵城市道路的铺设外，还可用于建筑承重墙的搭建。
