Lightweight aggregate concrete block and preparation method thereof

FEI JUQUAN

The invention relates to the field of concrete member production, in particular to a lightweight aggregate concrete block which comprises a first layer and a second layer, the first layer is provided with first aggregate, the particle size of the first aggregate in the depth direction is gradually increased within the range of 0.5-10 mm, the first aggregate is gradually dense in the direction close to the surface layer, and the second layer permeates into the first layer; the invention also discloses a preparation method of the lightweight aggregate concrete block, the concrete block obtained by the method is locally reinforced on the basis of the traditional lightweight aggregate concrete, and the self weight and the strength of the concrete block are balanced.

本发明涉混凝土构件生产领域，具体涉及一种轻骨料混凝土砌块，包括第一层与第二层，所述第一层具有第一骨料，所述第一骨料在深度方向上粒径在0.5‑10mm范围内逐渐增加，在靠近表层的方向上逐渐密实，所述第二层渗透入所述第一层；本发明还公开了一种轻骨料混凝土砌块的制备方法，利用该种方法获得的混凝土块，在传统轻骨料混凝土的基础上进行局部加强，在混凝土砌块自重与强度之间进行平衡。
