The invention discloses a sintering-free fly ash brick and a preparation method thereof, and belongs to the technical field of building materials. The sintering-free fly ash brick comprises the following raw materials: fly ash, boiler slag, carbide slag, calcium carbonate, calcium chloride, sodium sulfate, sodium silicate, deionized water, modified lignin, calcium lignosulphonate, cement and slaked lime. The preparation method of the sintering-free fly ash brick comprises the following steps: 1, weighing the raw materials in parts by weight; 2, mixing the weighed raw materials, grinding and refining to prepare a uniform mixed material; 3, carrying out static compression molding on the mixed material under the conditions that the pressure is 15-25MPa and the compression time is 5-10s, so as to obtain a green brick body; and conveying the green brick body into a still kettle, carrying out constant-temperature and constant-pressure still pressing for 8-12 hours under the conditions of 174-195 DEG C and 0.8-1.5 MPa, and taking the green brick body out of the still kettle to obtain the sintering-free fly ash brick.
本发明公开一种免烧结粉煤灰砖及其制备方法，属于建筑用材技术领域，该免烧结粉煤灰砖，包括如下原料，粉煤灰、锅炉炉渣、电石渣、碳酸钙、氯化钙、硫酸钠、硅酸钠、去离子水、改性木质素、木质素磺酸钙、水泥和熟石灰；该免烧结粉煤灰砖的制备方法包括如下步骤：第一步、按照重量份称取原料；第二步、将称量好的原料进行混料、研磨细化后，制备成均匀的混合物料；第三步、将混合物料在压力15‑25MPa，压制时间5‑10s的条件下，静态压制成型，获得砖坯体；将砖坯体，输送到蒸压釜中，在174‑195℃，0.8‑1.5MPa的条件下，恒温恒压蒸压8‑12h后，出蒸压釜，得到该免烧结粉煤灰砖。
