Aerated concrete plate and preparation process thereof

XU ZHENWEN

The invention relates to an aerated concrete plate and a preparation process thereof. The aerated concrete plate comprises the following components: a solid waste material, cement, lime, a foaming agent, a water reducing agent, a toughening agent and toughening short fibers, wherein the toughening short fibers are densely distributed on the surface layer of the aerated concrete plate in a net shape. According to the method, the limiting layer composed of the toughened short fibers is attached to the inner surface of the mold in advance before mold pouring, so that after pouring is completed, the toughened short fibers can be fully fused with concrete slurry, and the toughened short fibers are attached to the surface layer of a slab after the concrete slurry is completely solidified into the slab; the toughened short fiber can greatly improve the surface toughness and strength of the plate blank, is beneficial to reducing the damage of corners and edges of the plate blank in the demolding and cutting processes, and is beneficial to improving the product quality of the aerated concrete plate; the product contains the flexibilizer, so that the anti-shearing performance of the product can be obviously improved.

本发明涉及一种加气混凝土板材及其制备工艺。它包括以下组份：固废材料、水泥、石灰、发气剂、减水剂、增韧剂和增韧短纤维，所述增韧短纤维呈网状密布在所述加气混凝土板材的表层。本发明通过在模具浇筑前，提前在模具内表面附着一层由增韧短纤维构成的限位层，这样浇筑完成后，增韧短纤维可以与混凝土料浆充分融合，并在混凝土料浆完全固化为板坯后，附着于板坯的表层，该增韧短纤维可以极大提高板坯的表层韧性和强度，有助于在脱模、切割过程中减少板坯边角和棱边的破损，有助于提高加气混凝土板材的产品质量；产品内包含增韧剂，可以明显提高产品的抗剪切性能。
