混凝土裂缝问题一直严重困扰着混凝土的施工质量,在混凝土生产以及施工过程中有针对性地采取预防措施,尽可能采取有效的技术措施控制裂缝,使结构尽量不出现裂缝,或尽量减少裂缝的数量和宽度,特别是避免有害裂缝的出现,以确保工程质量,使建筑物具备良好的耐久性和结构稳定性。大量裂缝的出现,并非与荷载作用有直接关系,通过大量的调查与实测研究证明这种裂缝是由于变形作用引起,包括温度变形(水泥的水化热、气温变化、环境生产热),收缩变形(塑性收缩、干燥收缩、碳化收缩)及地基不均匀沉降(膨胀)变形。由于这些变形受到约束引起的应力超过混凝土的抗拉强度导致裂缝,统称“变形作用引起的裂缝”。在建筑工程中裂缝几乎无所不在。

The concrete crack problem has been perplexing the construction quality of concrete seriously, having already adopted prevention measure to sex ground in the concrete the production and the construction the process, adopting valid technique measure and controling crack possibly, making the structure don't appear crack as far as possible, or reduce amount and width of crack as far as possible, avoiding the emergence of harmful crack especially to insure engineering quality, making the building have good durable and structure stability.The emergence of a great deal of crack, carry with lotus not the function contain direct relation, passing a great deal of inquisition and measuring research to prove this kind of crack to is in order to transforming a function to cause actually, including temperature to transform(water of the cement turn hot, air temperature variety, environment produce hot), the constringency transforms(constringency, dry constringency, carbonization constringency
