自密实混凝土受弯梁受力性能试验

对自密实混凝土受弯梁的受力性能进行试验研究,通过试验得出自密实混凝土受弯梁的开裂荷载、抗弯承载力、抗剪承载力、构件延性和破坏形态,并与普通混凝土梁进行对比分析。试验结果表明:自密实混凝土梁在竖向荷载作用下,承载能力与破坏特征和普通混凝土梁相近,自密实混凝土梁具有良好的抗弯性能,阻裂性能和变形性能,其承载能力与普通混凝土相比有所提高。

Flexure bearing property experiment of self-compacting concrete beams

The flexure bearing properties of self-compacting concrete beams were conducted and bore cracking loads,tested flexural strength,shear strength,ductility of members,and failure forms were studied.Then,comparisons of basic properties were made between the self-compacting and normal concrete members.The results showed that the bearing capacity and failure characteristics were similar between self-compacting and normal concrete beams.Bending properties,crack resistance and deformation properties of self-compacting concrete beams were better than that of normal concrete beams.The bearing capacity of beam was improved by self-compacting concrete.
