Residue soil baking-free brick and preparation method thereof
The invention discloses a residue soil baking-free brick and a preparation method thereof, and relates to the technical field of baking-free bricks. The baking-free brick is formed by pressing 40-60%of muck, 10-20% of fly ash, 10-20% of cement, 10-20% of brick-concrete construction waste and 0.5-2% of lime as raw materials, a soil curing agent does not need to be doped any more, the specific gravity of solid waste in the raw material components reaches 78% or above, particularly, the 7-day strength of the baking-free brick is larger than 15 MPa, and the softening coefficient is larger than 0.8. The problems of high production cost, poor water stability and small specific gravity of solid wastes of the muck baking-free brick in the prior art are solved, the doping amount of the solid wastes such as muck, fly ash and construction wastes is increased on the premise of ensuring the compressive strength of the baking-free brick, the production cost is reduced, and the method is more economical and environment-friendly.
本发明公开了一种渣土免烧砖及其制备方法，涉及免烧砖技术领域。该免烧砖是以包括渣土40‑60%、粉煤灰10‑20%、水泥10‑20%、砖混建筑垃圾10‑20%和石灰0.5‑2%作为原料压制成型，不再需要掺加土壤固化剂，而且原料组分中固废料的比重达到78%以上，尤其是该免烧砖的7天强度＞15MPa，软化系数＞0.8，达到MU15的等级要求，解决了现有技术中渣土免烧砖生产成本高、水稳定性差及固废料比重小的问题，实现了在保证免烧砖抗压强度的前提下，增加了渣土、粉煤灰和建筑垃圾等固废料的掺加量，降低了生产成本，更加经济环保。
