Residue soil baking-free brick prepared from high-temperature modified residual mud and preparation method of residual soil baking-free brick
The invention discloses a muck baking-free brick using high-temperature modified residual mud and a preparation method thereof.The muck baking-free brick is prepared from calcined residual mud, cement, engineering muck and water, the dry mass ratio of the calcined residual mud to the cement to the engineering muck is 15: 85: 900, the water content of the engineering muck is smaller than 1%, the particle size of the engineering muck is smaller than 5 mm, and the water content of the engineering muck is smaller than 10%. The calcined residual mud is formed by calcining residual soil and residual mud with the particle size of less than 0.15 mm in granite weathered residual soil. The invention further provides a preparation method of the residue soil baking-free brick using the high-temperature modified residue soil. According to the invention, the kaolin component in the granite weathered residual soil residual mud is fully utilized and is changed into the calcined residual mud with pozzolanic activity through simple treatment, and the calcined residual mud is used as a mineral admixture to partially replace cement, so that the cost is reduced, and the carbon emission generated by using the cement can be reduced while the strength is ensured.
本发明公开了一种使用高温改性余泥的渣土免烧砖及其制备方法，渣土免烧砖的原料包括煅烧余泥、水泥、工程渣土和水，煅烧余泥、水泥和工程渣土的干质量比为15∶85∶900，工程渣土的含水率小于1％，工程渣土的粒径小于5mm，煅烧余泥为花岗岩风化残积土中粒径小于0.15mm的残积土余泥煅烧而成。本发明还提供了一种使用高温改性余泥的渣土免烧砖的制备方法。本发明充分利用了花岗岩风化残积土余泥中的高岭土成分，经简单处理变成具有火山灰活性的煅烧余泥，其作为矿物掺合料部分取代水泥，不仅降低成本，而且能够在保证强度的同时降低使用水泥产生的碳排放。
