【摘要】 结合具体工程,阐述了现浇钢筋混凝土连续式结构不设伸缩缝的理论依据,论述了UEA(硫铝酸钙类膨胀剂)补偿混凝土的抗裂机理,从设计、技术、施工方面对不设永久伸缩缝提出了有效控制裂缝的措施。更多还原

【Abstract】 In combination with concrete project,theoretic basis was described for the continuous structure for cast-in-site reinforcement concrete without expansion joint,anti-crack mechanism was discussed for UEA(aluminium calcium sulfate swelling agent) compensate concrete,measure for effectively controlling crack was presented for concrete without permanent expansion joint from aspects of design,technique,construction.更多还原
