 摘要:装配式建筑中拼装接缝的处理是施工难点,结合工程应用,采用可再分散乳胶粉、水泥、橡胶粉等制备了一种接缝胶泥,该胶泥满足装配式建筑中叠合板接缝材料对拉伸粘结强度、定伸粘结性及耐久性等指标的要求。试验结果表明,可再分散乳胶粉的掺入,提高了胶泥的拉伸粘结强度和断裂伸长率;橡胶粉的掺入提高了胶泥的断裂伸长率,降低了成本,有利于胶泥的推广应用。

Abstract:The treatment of joint of prefabricated building is a construction difficulty. According to the engineering application,a joint mortar was prepared with redispersible emulsion powder,cement and rubber powder. The mortar met the requirements of the tensile bond strength,tensile adhesion and durability of the joint material in the prefabricated building. The experiment showed that the addition of redispersible emulsion powder increased the tensile bond strength and elongation at break of the mortar. The addition of rubber powder increased the elongation at break of the mortar and reduced the cost,and is conducive to the promotion and application of mortar.
