The invention belongs to the technical field of concrete bricklaying, and particularly relates to a lightweight aggregate concrete block and a preparation method thereof.The preparation method comprises the following steps that S1, aggregate and cement are added into a mixing device according to the weight ratio of 1: 2.5-2.9, water is added, and mixing is performed to form a mixture; s2, preparing aerated concrete slurry with lightweight aggregate; s3, a building block mold is prepared, a mixture is laid at the bottom of the building block mold, transverse vibration is applied to the mold, and then compaction is conducted; s4, an opening in the upper portion of the building block mold is closed, vibration is kept in the foaming process of the aerated concrete slurry, the building block mold is turned over after the building block mold is filled with the aerated concrete slurry, and the building block mold is placed in a negative pressure environment for static precuring till foaming is completed; and S5, after demolding, sending the building block into a still kettle for curing. According to the light-weight aggregate concrete brick forming device, in the material stirring process, a mixture is fully mixed through the material stirring device, the mixing uniformity of the mixture is ensured, and therefore the quality of formed light-weight aggregate concrete bricks is ensured.
本发明属于混凝土砌砖技术领域，尤其是一种轻骨料混凝土砌块及其制备方法，包括如下步骤：S1、将骨料与水泥按照重量比例1:2.5‑2.9的比例加入拌料装置中，加水混合，形成拌和物；S2、制备具有轻骨料的加气混凝土浆料；S3、准备砌块模具，在砌块模具底部铺设拌和物，对模具施加横向振动，然后振实；S4、对砌块模具上部开口封闭，在加气混凝土浆料发泡过程中保持振动，待砌块模具内充满后翻转砌块模具，将砌块模具置于负压环境中静止预养，待其发泡完成；S5、脱模后将砌块送入蒸压釜养护。本发明中，在拌料时，通过拌料装置对拌合物进行充分混合，确保拌合物混合的均匀性，从而确保成型的轻骨料混凝土砌砖的质量。
