Fly ash-based impervious material and application thereof
The invention relates to the field of C04B14/02, and particularly provides a fly ash-based impervious material which is prepared from the following raw material components in percentage by mass: 50 to 85 percent of fly ash, 3 to 20 percent of alkaline substances containing calcium ions, 2 to 20 percent of cement and the balance of other solid wastes. The fly ash is specified to be high-alkalinity fly ash, the alkaline substance containing calcium ions is preferably quicklime, and the mass ratio of the fly ash to the alkaline substance containing calcium ions is (6-8): 1, so that the activity of the fly ash can be effectively excited, the use amount of cement in the anti-permeability material is reduced to 3-10%, the cost is effectively reduced, and the anti-permeability material is suitable for large-scale production. And the anti-seepage material has proper compressive strength and excellent anti-seepage performance.
本申请涉及C04B14/02领域，具体提供了一种粉煤灰基抗渗材料，按总质量计，所述抗渗材料的原料组分包括：粉煤灰50‑85％、含钙离子的碱性物质3‑20％、水泥2‑20％、其他固体废料补充余量为100％。通过规定粉煤灰为高碱性粉煤灰，含钙离子的碱性物质优选为生石灰，粉煤灰和含钙离子的碱性物质的质量比为(6‑8)：1，可有效激发粉煤灰活性，使抗渗材料中水泥的使用量低至3‑10％，有效降低成本，并且使该抗渗材料具有合适的抗压强度和优异的抗渗性能。
