摘 ? 要:分析了兩類超高性能混凝土(UHPC)在裝配式建筑中的應用前景與相應的質量指標體系。結果表明:結構類超高性能混凝土可用于裝配式漿錨搭接與裝配式預制構件中,建議其抗壓強度不低于120 MPa、抗彎強度不低于14 MPa、抗拉強度不低于7 MPa;裝飾類超高性能混凝土可用于裝配式建筑外墻裝飾,建議其抗壓強度不低于100 MPa、抗彎強度不低于10 MPa、抗拉強度不低于5 MPa;裝配式建筑用超高性能混凝土的28 d干縮不宜大于300 με,3 d自收縮不大于800 με,28 d氯離子擴散系數不宜大于0.30×10-12 m2/s。
Abstract: The application prospect and corresponding quality index system of two kinds of ultra-high performance concrete(UHPC) in prefabricated buildings were analyzed. The results show that the structural ultra-high performance concrete can be used in the assembly type of slurry anchor lap and assembly type of prefabricated components, and its compressive strength is not less than 120 MPa, bending strength is not less than 14 MPa, and tensile strength is not less than 7 MPa. Decorative ultra-high performance concrete can be used for decoration of exterior wall of prefabricated building. It is suggested that its compressive strength should not be less than 100 MPa, bending strength should not be less than 10 MPa and tensile strength should not be less than 5 MPa. The 28 d dry shrinkage of UHPC for prefabricated building should not be greater than 300 με, the 3 d self shrinkage should not be greater than 800 με, and the 28 d chloride diffusion coefficient should not be greater than 0.30×10-12 m2/s.
