Autoclaved porous brick and preparation method thereof
The invention provides an autoclaved porous brick. The autoclaved porous brick comprises the following components in percentage by mass: 10-20% of a curing material, 20-30% of slag, 20-30% of fly ash and 40-50% of gravel; and the curing material comprises the following components in percentage by mass: 20-30% of mineral powder, 50-60% of clinker, 10-20% of lime and 1-8% of an additive. The preparation method of the autoclaved porous brick comprises the following steps: S1, preparing the curing material; S2, preparing raw materials; S3, digesting a mixture; S4, crushing; S5, forming and stacking; S6, steaming and pressing; and S7, detecting. The autoclaved porous brick has the beneficial effects that the cost is reduced by using the fly ash, the compressive strength of the autoclaved porous brick is improved by increasing the proportion of the curing material, and the autoclaved porous brick is ensured to meet performance requirements; the mineral slag is used for replacing cement clinker and lime, so that the density of the autoclaved porous brick is reduced, the compressive strength of the autoclaved porous brick is improved, and the pore-forming rate of the autoclaved porous brick is improved by utilizing irregular surfaces of particles of the mineral slag.
本发明提供了一种蒸压多孔砖，包括以下质量分数计的组分：固化材料10‑20％、炉渣20‑30％、粉煤灰20‑30％以及砂石40‑50％；所述固化材料包括以下质量分数计的组分：矿粉20‑30％、熟料50‑60％、石灰10‑20％以及外加剂1‑8％；一种蒸压多孔砖的制备方法，包括以下步骤：S1固化材料制备；S2原料制备；S3混合料消化；S4粉碎；S5成型码垛；S6蒸压；S7检测；本发明的有益效果：通过使用粉煤灰降低成本，通过提高固化材料比例提高蒸压多孔砖的抗压强度，保证蒸压多孔砖满足性能要求；通过用矿渣代替水泥熟料、石灰，降低蒸压多孔砖的密度，提高蒸压多孔砖的抗压强度，利用矿渣的颗粒的表面不规整，提高蒸压多孔砖的成孔率。
