Lightweight high-strength ceramsite and preparation method thereof
The invention provides a lightweight high-strength ceramsite and a preparation method thereof. The lightweight high-strength ceramsite comprises a mixed material and a pore forming agent at a mass ratio of 100:1.5-3; the mixed material comprises, by weight, 5 to 15 parts of kaolin tailing, 55 to 65 parts of coal gangue, and 20 to 40 parts of fly ash. The preparation method comprises following steps: kaolin tailing, coal gangue, and fly ash are mixed, and an obtained mixture is subjected to grinding, and sieving using a sieve of 0.16mm; the pore forming agent is added, an obtained product is mixed uniformly, water is added, and an obtained material is stirred and is subjected to moulding until desired size is achieved so as to obtain a ceramsite raw batch; the ceramsite raw batch is delivered into a high temperature furnace for 10 to 20min of thermal insulation at 1050 DEG C so as to finish sintering. According to the preparation method, the raw materials are all wastes; waste utilization rate is as high as 100%; and the lightweight high-strength ceramsite can be obtained via sintering at low temperature.
