摘要: 针对两个强度等级的混凝土,制作了6块自密实混凝土和2块普通混凝土双向板,通过试验研究了自密实混凝土双向板的抗弯性能。结果表明:1)自密实混凝土双向板极限荷载实测值与同强度等级普通混凝土双向板极限荷载实测值相差不大,且明显高于其理论计算值;2)两者的荷载-挠度曲线形状、裂缝发展规律和破坏形态基本一致;3)自密实混凝土双向板裂缝宽度较小且分布均匀。因此,采用普通混凝土结构理论设计自密实混凝土双向板是安全的。

Abstract: To study anti-bending properties of self-compacting concrete dual-way slabs,six self-compacting and two corresponding ordinary concrete dual-way slabs of two different strength grade are made.The results show that:1) the experimental data of limit load of self-compacting concrete dual-way slabs are close to those of the ordinary concrete dual-way slab with same strength grade,and are obviously higher than their theoretical value;2) the load-deflection curves,the crack development and the broken shapes of the two kinds of dual-way slabs are basically the same;3) compared with ordinary concrete dual-way slabs,the cracks in self-compacting concrete dual-way slabs appear to be with smaller width and spread more evenly.Therefore,it is safe to design the self-compacting concrete dual-way slab according to the theory of ordinary concrete.
