Method for preventing basement exterior wall concrete from generating cracks
The invention belongs to the technical field of concrete, and particularly relates to a method for preventing basement exterior wall concrete from cracking. The method for preventing the basement outer wall concrete from cracking comprises the following steps that after basement bottom plate concrete is poured and hardened, outer wall plate steel bars are bound, a reinforcing formwork is installed, and then a layer of special concrete is poured along the bottom of the outer wall formwork and the upper portion of a basement bottom plate and an outer wall horizontal construction joint to form a deformation coordination belt; then, common concrete is poured on the upper portion of the deformation coordination zone immediately, and maintenance with a mold is carried out; the layer height of the deformation coordination zone is greater than or equal to 400mm and greater than or equal to the thickness of the external wall panel; the special concrete is obtained by mixing cement, fly ash, mineral powder and an expanding agent to obtain a cementing material, adding broken stone, sand, a water reducing agent, reinforced fibers and water, and stirring and mixing. The concrete deformation coordination belt is arranged at the bottom of the basement external wall panel, constraint of the basement bottom plate to the wall panel concrete is reduced, and therefore the basement wall panel concrete is prevented from cracking.
本发明属于混凝土技术领域，具体涉及一种防止地下室外墙混凝土产生裂缝的方法。所述防止地下室外墙混凝土产生裂缝的方法，包括以下步骤：在地下室底板混凝土浇筑硬化后，绑扎外墙板钢筋并安装加固模板，然后沿外墙模板底部，地下室底板与外墙水平施工缝上部，浇筑一层特种混凝土形成变形协调带，随后立即在变形协调带的上部浇筑普通混凝土，并带模养护；变形协调带的层高大于等于400mm，且大于等于外墙板厚度；特种混凝土是将水泥、粉煤灰、矿粉和膨胀剂混合得到胶凝材料，再加入碎石、砂、减水剂、增强纤维与水搅拌混合得到。通过在地下室外墙板底部设置混凝土变形协调带，减少地下室底板对墙板混凝土约束，从而防止地下室墙板混凝土产生裂缝。
