摘要
与普通钢筋混凝土梁相同,基体混凝土的强度等级、纵筋配筋率、钢筋的强度等级影响着自密实全轻骨料混凝土梁受弯性能。钢纤维使自密实轻骨料混凝土梁受弯能力得到了明显的提升。
The same with ordinary reinforced concrete beams,the strength grade of matrix concrete,the ratio of longitudinal reinfocement and the strength grade of reinforcement are the main factors affecting the flexural behaviour of self-compacing light-aggregate concrete beams.Incorporation of steel fibers has made bending capacity of self-compacing light-aggregate concrete beams significantly improved.
