Ceramsite prepared from gasified slag and preparation method thereof
The invention provides ceramsite prepared from gasified slag and a preparation method of the ceramsite, and the ceramsite is prepared from the following raw materials in parts by weight: 80-100 parts of gasified fine slag, 0-20 parts of a binder, 0-10 parts of carbon powder and 40-60 parts of a water glass solution, wherein the mass concentration of the water glass solution is 24.5-46%, the modulus of the water glass solution is 1.0-2.4, and the binder comprises one or more of fly ash, gasified coarse slag or furnace bottom slag; the dry basis carbon content of the gasified fine slag is 10-40%, and the total amount of SiO2 and Al2O3 in the dry basis of the gasified fine slag except carbon is greater than or equal to 50%. According to the ceramsite provided by the invention, the gasified fine slag is used as a main raw material, and the water glass solution is used as an active exciting agent and a fluxing agent, so that the prepared ceramsite has excellent apparent density and porosity.
本发明提供了一种气化渣制备的陶粒及其制备方法，陶粒由以下原料制备得到：以所述原料的重量份计，气化细渣80～100重量份，粘结剂0～20重量份，碳粉0～10重量份，水玻璃溶液40～60重量份；其中，水玻璃溶液的质量浓度为24.5～46％，模数为1.0～2.4，粘结剂包括粉煤灰、气化粗渣或炉底渣中的一种或多种；气化细渣的干基含碳量为10～40％，气化细渣的干基中除碳以外，SiO2与Al2O3的总量≥50％。本发明提供的陶粒以气化细渣为主要原料，水玻璃溶液作为活性激发剂和助熔剂，制得的陶粒具有优异的表观密度和空隙率。
