预拌混凝土的高收缩性是产生混凝土裂缝的主要原因之一,早期混凝土裂缝与施工图设计、配合比设计、原材料质量有关,但与施工现场的浇筑工艺、施工环境及养护更为关联,笔者从施工现场的角度阐述早期混凝土裂缝的控制方法。 The high shrinkage of ready-mixed concrete is one of the main causes of concrete cracks. The early concrete cracks are related to the design of construction drawings, mix design and quality of raw materials, but are more related to the pouring process, construction environment and maintenance of construction site. The Control Method of Early Concrete Crack from the Construction Site.
