Baking-free brick containing aluminum mud
The invention discloses a baking-free brick containing aluminum mud, which is prepared from the following materials in percentage by weight: 15-25% of dry aluminum mud powder, 3-10% of fly ash, 5-20% of water-quenched slag powder, 5-15% of Portland cement and 20-50% of sandstone aggregate, and the aluminum mud is a solid waste filler. The sandstone aggregate can also be replaced with industrial and mining solid waste to serve as aggregate besides a common sandstone material, and the aggregate comprises but is not limited to tailing sand, barren rock and construction waste. The curing cementing material comprises but is not limited to fly ash, water-quenched slag powder and Portland cement. The invention relates to the technical field of construction materials, in particular to a baking-free brick containing aluminum mud. The expansion damage of the baking-free brick caused by water absorption of the aluminum mud is inhibited, and the stability of the product is improved. The characteristics of a volcanic ash material and dense filling of coarse and fine aggregate gradation are fully utilized, so that the use amount of cement is reduced, the cost is greatly reduced, the volume weight and strength of a product are increased, and the negative influence of light aluminum mud on the strength of the product is reduced.
本发明公开了含铝泥之免烧砖，由以下材料重量配比制成：干燥铝泥粉15‑25％、粉煤灰3‑10％、水淬渣粉5‑20％、硅酸盐水泥5‑15％、砂石骨料20‑50％，其中铝泥为固废填充料。所述砂石骨料除了一般砂石材料，也可替换为工矿业固废作为骨材，包括但不限于尾矿砂、废石和建筑废弃物。固化胶结料包括但不限于粉煤灰、水淬渣粉和硅酸盐水泥。本发明涉及营建材料技术领域，具体涉及含铝泥之免烧砖。抑制铝泥吸水造成免烧砖的膨胀破坏，提高产品的安定性。充分利用火山灰材料特性和粗细骨料级配的致密填充，不仅减少水泥的使用量，大幅降低成本，并且增加了产品的容重与强度，降低了轻质铝泥对产品强度的负面影响。
