Residue soil baking-free brick and preparation method thereof
The invention discloses a residue soil baking-free brick and a preparation method thereof, and belongs to the technical field of building materials and environmental engineering. The preparation method comprises the following steps: pretreating undisturbed muck, spraying a soil curing agent into semi-dry muck fine powder, uniformly stirring, uniformly mixing the active cementing material and the modified muck fine powder, loading the powder mixture into a mold, and pressing the powder mixture into a high-density block body in the mold under high forming pressure of 50-80 MPa; crushing and grinding the high-density block, and then performing screening and grading treatment; weighing materials with different particle sizes, uniformly stirring, loading a particle powder mixture into a mold, and pressing into a residue soil brick blank body in the mold; and standing and curing the residue soil brick blank to obtain the residue soil baking-free brick. Compared with a traditional residue soil baking-free brick, the residue soil baking-free brick prepared through the method is high in residue soil utilization rate, high in density, high in strength and low in water absorption rate and shows high market competitiveness as a novel wall material, and large-scale cyclic regeneration resource utilization of residue soil is achieved.
本发明公开了一种渣土免烧砖及其制备方法，属于建筑材料与环境工程技术领域。制备方法包括将原状渣土进行预处理，向半干渣土细粉料中喷洒土壤固化剂并搅拌均匀，将活性胶凝材料和改性渣土细粉料均匀混合，将粉末混合料装入模具中，以50～80MPa高成型压力将粉末混合料在模具中压制成高致密块体；将高致密块体进行破碎、打磨，随后筛分分级处理；称取不同粒径物料并搅拌均匀后将颗粒粉末混合料装入模具，在模具中压制成渣土砖坯体；将渣土砖坯体静置养护，得到渣土免烧砖。本发明制备渣土免烧砖与传统渣土免烧砖相比，渣土利用率高、致密度高、强度高、吸水率低，作为新型墙体材料，体现出较强市场竞争力，实现渣土大批量循环再生资源化利用。
