塑钢纤维轻骨料混凝土轴心受压应力-应变全曲线试验研究
Experimental Study on Axial Compressive Stress-Strain Full Curve of the Plastic Steel Fiber Lightweight Aggregate Concrete
摘要
Abstract
The influence of various water-binder ratio,plastic steel fiber content and light aggregate type was studied on stress-strain curves of lightweight aggregate concrete with plastic steel fiber,the influence laws of each factor was obtained on the full curve.The result of research indicate that the increase in the ratio of water binder, the peak stress of the compressive stress-strain curve have decreased in different degrees,but there is a slight increase in peak strain, toughness and ductility have improved; With the increase of plastic fiber content, the axial compressive strength of plastic fiber reinforced lightweight aggregate concrete first increases and then decreases.The peak stress increases with the pressure strength of the cylinder.关键词
