Lightweight thermal-insulation aerated building block and preparation method thereof
The invention relates to the field of building materials, and particularly discloses a lightweight thermal-insulation aerated building block and a preparation method thereof. The preparation method of the lightweight thermal-insulation aerated building block comprises the following steps: step 1) uniformly mixing water, a thickening agent and acetone to obtain an acetone solution; 2) adding cement, fly ash, lime and sand into an acetone solution, and uniformly mixing to obtain a mixed material; the method comprises the following steps of (1) preparing a mixture, (2) adding the mixture into a mold, (3) pouring the mixture into the mold to form a blank body, (4) heating and steam-curing the blank body for 120-130 minutes at the steam-curing temperature of 48-49 DEG C, (5) raising the steam-curing temperature to 54.5-55 DEG C and steam-curing for 80-85 minutes, (6) raising the steam-curing temperature to 60-61 DEG C and steam-curing for 5-6 hours, and (7) demolding to obtain the lightweight heat-insulating aerated building block.
本发明涉及建材领域，具体公开了一种轻质保温的加气砌块及其制备方法。一种轻质保温的加气砌块的制备方法，包括以下步骤：步骤1），将水、增稠剂、丙酮混合均匀，得丙酮溶液；步骤2），将水泥、粉煤灰、石灰、砂投入丙酮溶液中，混合均匀，得拌和料；步骤3），将拌和料浇筑至模具中，形成胚体；步骤4），将胚体加热蒸养，蒸养温度为48‑49℃，蒸养120‑130min；步骤5），蒸养温度上升至54.5‑55℃，蒸养80‑85min；步骤6），蒸养温度上升至60‑61℃，蒸养5‑6h；步骤7），脱模，得轻质保温的加气砌块。本发明具有提高加气砌块的抗压强度的优点。
