摘要
一直以来,水泥混凝土桥面铺装带来的混凝土开裂问题使人们深受困扰,而致密、抗裂性能强的自应力混凝土能有效地缓解这一问题。根据实际情况,本试验通过对自应力混凝土的膨胀率和力学性能进行深入分析,并对膨胀率的使用量进行研究。
The problem of concrete cracking caused by cement concrete bridge deck paving has always been deeply troubled,and the dense,self-stressed concrete with strong crack resistance can effectively alleviate this problem.According to the actual situation,this test conducts in-depth analysis of the expansion rate and mechanical properties of self-stressed concrete,and studies the amount of expansion rate used.
