Production process of autoclaved lightweight concrete slab
The invention provides a production process of an autoclaved lightweight concrete slab. The production process of the autoclaved lightweight concrete slab comprises the following steps that S1, concrete slurry is mixed to be uniform and then injected into a mold, and the surface of concrete is flattened and compacted; s2, putting the concrete into a constant-temperature and constant-humidity box, and standing and maintaining for 12-24 hours under the conditions that the temperature is 50-60 DEG C and the relative humidity is 90-95%; s3, transferring the solidified concrete into a still kettle, and carrying out constant-temperature and constant-pressure still-pressure reaction for 8-12 hours; and S4, the concrete slabs are placed on an open space to be watered and maintained for 5-7 days, demolding is conducted, and the concrete slabs are cut into the concrete slabs with the needed size after demolding. The strength of the fly ash can be improved by adding the composite silicon dioxide, on one hand, due to the fact that composite silicon dioxide particles are small, micropores of the fly ash can be filled with the composite silicon dioxide particles, the compact filling effect is achieved, and the compressive strength of the fly ash is improved;
本发明提供了一种蒸压轻质混凝土板生产工艺。所述蒸压轻质混凝土板生产工艺包括如下步骤：S1：将混凝土浆料混合至均匀后注入模具中，将混凝土表面抹平压实；S2：将混凝土放入恒温恒湿箱中，在温度为50‑60℃，相对湿度90‑95％的条件下，静置养护12‑24h；S3：混凝土固化后转入蒸压釜进行恒温恒压蒸压反应8‑12h；S4：再放在空地上浇水养护5‑7d，在进行脱模，脱模后被切割成所需尺寸的混凝土板。通过将加入复合二氧化硅可以改善了粉煤灰的强度，一方面由于复合二氧化硅颗粒较小，能够填充在粉煤灰的微细孔中，起到填充密实的作用，使其抗压强度提高。
