Crack control method for cast-in-place concrete shear wall
A cast-in-place concrete shear wall crack control method comprises the steps that shrinkage compensation concrete is prepared according to the proportion and poured into a shear wall formwork, and the proper slump, layering thickness and vibration interval of the concrete are controlled; controlling the in-mold temperature of the concrete and the temperature rise after the concrete enters the mold, and controlling the inner-surface temperature difference and the cooling rate of the concrete pouring body and the temperature difference between the surface of the pouring body and the environment; two sensors for detecting surface and center temperature and deformation data of the shear wall are respectively arranged at proper positions of the shear wall; data of the two sensors are read every one hour; when the difference between the temperature of the center of the shear wall and the environment temperature is smaller than or equal to 25 DEG C, the formworks on the two sides of the shear wall are dismantled, and maintenance is conducted immediately. By adopting a series of measures, the overall continuity of the cast-in-place shear wall structure is enhanced, a good crack control effect is achieved, repeated maintenance in the later use stage is avoided, the durability of concrete is improved, the service life of the concrete is prolonged, and high economic benefits are achieved.
一种现浇混凝土剪力墙裂缝的控制方法，包括把按比例配制补偿收缩混凝土，浇筑至搭设剪力墙模板内，控制混凝土合适的坍落度、分层厚度和振捣间距；控制混凝土的入模温度和入模后的温升，控制混凝土浇筑体的里表温差、降温速率和浇筑体表面与环境温差；在剪力墙适当位置分别布置两个用于检测其表面和中心温度、变形数据的传感器；每间隔1小时分别读取两个传感器的数据；剪力墙中心的温度与环境温度之差≤25℃时，拆除剪力墙两侧的模板，并立即进行养护。本发明通过采取一系列措施，增强现浇剪力墙结构的整体连续性，实现了较好的裂缝控制效果，避免后期使用阶段的反复维修，提高混凝土的耐久性和使用寿命，具有较高的经济效益。
