摘　　要：在混凝土墙体材料逐渐推广的背景下,新型混凝土砌块开始逐渐得到推广和发展,但其墙体裂缝问题一直是影响混凝土砌块墙体质量的关键因素。新型混凝土砌块裂缝的主要特点为干缩性增加、收缩率大并且参数不符合标准,而造成混凝土砌块墙体出现裂缝的主要原因包括原材料问题、设计问题及工艺操作问题。针对混凝土砌块墙体裂缝的具体处理策略,包括对墙体裂缝的鉴别和对墙体裂缝的处理,而降低发生混凝土砌块墙体裂缝机率的具体措施为全过程质量控制。With the gradual popularization of concrete wall materials, new concrete blocks begin to be popularized and developed gradually. However, the crack problem of wall has always been the key factor affecting the quality of concrete block wall. The main features of the new concrete block cracks are increased shrinkage, large shrinkage and parameters do not meet the standards. The main causes of cracks in the concrete block wall include raw materials, design issues and process operation issues. Concrete treatment strategies for concrete block wall cracks, including the identification of wall cracks and wall cracks treatment, and concrete concrete wall to reduce the probability of cracking the concrete strategy for the whole process before and after the quality control.
