在混凝土施工过程中,刚浇注完成的混凝土上表面不能被模板等物覆盖而裸露在大气中,由于种种原因,其表面往往在开始养护之前就产生裂缝,特别是夏季施工,具有较大水平表面的混凝土,裂缝产生更为突出。在砼路面的施工中,无论在技术上、管理上,仍有不少教训值得我们去反思研讨。尢其是水泥砼路面在夏季炎热季节施工期间易产生收缩裂缝,这种因混凝土收缩产生的裂缝叫做早期裂缝。它对于水泥混凝土路面的使用寿命有着极大影响,是水泥混凝土路面产生破损的主要原因之一,下面就如何防治水泥混凝土路面在炎热季节产生早期收缩裂缝谈一下个人看法,仅供参考。
In the concrete construction process, the concrete surface just finished pouring can not be covered by the template and other objects exposed to the atmosphere, due to various reasons, the surface often cracks before starting curing, especially in summer construction, with a larger horizontal surface Concrete, cracks are more prominent. In the construction of concrete pavement, no matter in technology, management, there are still many lessons worth our review to discuss. Especially cement concrete pavement during the hot season in the summer is easy to produce shrinkage cracks, cracks caused by concrete shrinkage is called early cracks. It has a great influence on the service life of cement concrete pavement, cement concrete pavement damage is one of the main reasons, the following on how to prevent cement concrete pavement in the hot season to produce early shrinkage cracks about personal opinion, for reference purposes only.
