Anti-freezing fly ash brick and preparation method thereof
The invention discloses an anti-freezing fly ash brick and a preparation method thereof, and belongs to the technical field of building materials. The fly ash brick comprises the following raw materials: fly ash, cement, lime, yellow sand, sodium nitrite, sodium sulfate, sodium silicate, triethanolamine, a waterproof agent and an additive. The preparation method of the fly ash brick comprises the following steps: 1, weighing the raw materials in parts by weight; and 2, mixing the weighed raw materials, then adding water to prepare a mixed material, pressing the mixed material into a mold under the pressure of 26 MPa to obtain a blank body, transferring the obtained blank body into a still kettle, and maintaining for 12 hours under the conditions of the pressure of 1-1.5 MPa and the temperature of 160-170 DEG C to obtain the anti-freezing fly ash brick. By adding the waterproof agent and the additive, the anti-freezing property of the fly ash brick is improved, and the stability of the fly ash brick is improved.
本发明公开一种抗冻粉煤灰砖及其制备方法，属于建筑用材技术领域，该粉煤灰砖包括如下原料：粉煤灰、水泥、石灰、黄沙、亚硝酸钠、硫酸钠、硅酸钠、三乙醇胺、防水剂和添加剂；该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、将称取的原料混合，然后加入水，制成混合物料，将混合物料在压力为26MPa下压入模具，得到胚体，将得到的胚体转移至蒸压釜中，在压力为1‑1.5MPa、温度为160‑170℃条件下养护12h，得到一种抗冻粉煤灰砖。本发明中通过添加了防水剂和添加剂，提高粉煤灰砖的抗冻性能，有利于提高粉煤灰砖的稳定性。
