Rail shield muck unburned and non-autoclaved ceramsite and preparation method thereof
The invention relates to a rail shield muck unburned and non-autoclaved ceramsite and a preparation method thereof. The rail shield muck unburned and non-autoclaved ceramsite comprises the following raw materials in parts by weight: 75-100 parts of rail shield muck, 3-5 parts of cement, 3-5 parts of quick lime, 3-5 parts of desulfurization gypsum, 5-10 parts of coal ash, 5-10 parts of water glass, 3-5 parts of sodium sulfate and 30-50 parts of water. The preparation method comprises the following steps: uniformly mixing the solid components; adding water to prepare the ceramsite; naturally maintaining at room temperature to obtain the rail shield muck unburned and non-autoclaved ceramsite. According to the rail shield muck unburned and non-autoclaved ceramsite and the preparation method thereof, the earlier-stage treatment of the shield muck is simple, the muck consumption is high, the preparation process is simple, high-temperature sintering is not required and the industrial waste such as coal ash and desulfurization gypsum can be digested; by adopting an unburned and non-autoclaved process, the preparation method has the advantages of being low in cost, energy-saving, low in carbon and environment-friendly when being compared with the sintering-method based ceramsite preparation process.
