摘要
摘 要:套筒灌浆料的应用性能对装配式建筑节点连接质量影响重大,但低温限制了套筒灌浆料性能的发挥。通过研究拌合水温度、环境温度对套筒灌浆料力学性能、接头试件抗拉性能以及施工应用性能的作用与影响,探索出了简便可行的套筒灌浆料冬期施工工艺。
Abstract: The application performance of cementitious grout for coupler of rebar splicing has a great influence on the quality of the connection of the assembled building. But low temperature has limited the performance exerting of cementitious grout for coupler of rebar splicing. The simple and feasible construction technology for cementitious grout for coupler of rebar splicing in winter period is studied through researching the effect and influence of mixing water temperature and ambient temperature on mechanical properties, tensile properties of joint specimens and construction application properties of the cementitious grout for coupler of rebar splicing.
