摘要
在混凝土中掺入膨胀剂（UEA）和粉煤灰,采用结构自防水及无缝施工技术,针对某公司办公楼地下室,将原后浇带位置改为“膨胀加强带”,带内用掺量占总胶凝材料用量12%的膨胀剂拌制的大膨胀混凝土浇筑,带间增加10～15%的水平温度筋,带的两侧分别架设孔径为5mm的钢丝网,并用立筋加固,整体结构外观质量良好,没有出现裂纹及渗漏现象,使混凝土具有结构自防水功能.
In this paper,expansion additive（UEA） and fly ash are added in the concrete. The self water-proof configuration and construction technique without any cracks are used in the basement of office block. Between the first axes and second axes, the position which is laterconcreted zone, called as ＂expansion reinforcement belt＂, where expansion additive dosage is 12 percent of all cementitious materials and almost 10 to15 percent of temperature reinforcing steel bar is increased. The steel wire gridding with 5 millimeter aperture is span at both sides of ＂expansion of strengthen region＂. Meanwhile, stand steel bar is used to be reinforced in this configuration.
