Anti-cracking detachable fiber cement board inner wall
The invention discloses an anti-cracking detachable fiber cement board inner wall. The anti-cracking detachable fiber cement board inner wall comprises symmetrically-arranged fiber cement board layers, wherein the fiber cement board layers are formed by splicing a plurality of fiber cement boards, mounting frames are fixed to the inner sides of the fiber cement board layers, and the mounting frames are connected through keels. Each fiber cement board is prepared from the following raw materials in parts by weight: 20-40 parts of cement, 30-50 parts of aggregate, 10-20 parts of a doping material, 4-8 parts of modified polyformaldehyde fibers, 3-5 parts of chopped basalt fibers, 1-3 parts of a water reducing agent, 0.5-2 parts of an anti-freezing agent and 15-30 parts of water. According to the anti-cracking detachable fiber cement board inner wall, the modified polyformaldehyde fibers and the basalt fibers are added into cement mortar, plastic deformation of concrete is restrained through composite fibers, and stress concentration of the concrete is dispersed, so that concrete cracking is delayed or avoided, and the cement board has better mechanical performance than a common fiber cement board.
本发明公开一种防开裂开拆卸式纤维水泥板内墙，包括对称设置的纤维水泥板层，限位水泥板层由若干纤维水泥板拼接而成，纤维水泥板层内侧固定安装架，安装架之间通过龙骨连接，纤维水泥板包括以下重量份原料：水泥20‑40份、骨料30‑50份、掺杂料10‑20份、改性聚甲醛纤维4‑8份、短切玄武岩纤维3‑5份、减水剂1‑3份、防冻剂0.5‑2份、水15‑30份。本发明通过在水泥砂浆中添加改性聚甲醛纤维和玄武岩纤维，通过复合纤维约束混凝土的塑性变形，分散混凝土的应力集中，从而推迟或避免混凝土开裂，比普通纤维水泥板具有更好的力学性能。
