摘要: 为了分析塑钢轻质骨料加入到混凝土中的力学以及粘结性能,基于试验研究并分析了影响混凝土试件力学以及粘结性能的影响因素,实验结果表明:加入不同比例的塑钢纤维混凝土试件的力学以及粘结性能均表现出了不同的变化特性,混凝土及砂浆的用水量、砂率的不同,会导致塑钢纤维对混凝土的增强效果差异较大;素混凝土的强度较高时,混凝土试件的粘结性能越高,并且其钢筋产生的位移大大降低;加入塑钢纤维的混凝土试件的力学以及粘结性能均会随着轻质骨料筒压的降低而降低。

关键词: 塑钢纤维轻骨料;力学性能;粘结强度

Abstract: In order to analysis the mechanical and the bond properties of the concrete, which added steel light aggregate. The mechanical and the bond performance between steel bar and HPP fiber reinforced lightweight aggregate concrete were analyzed based on the experience. The results show that the enhancement effect difference is bigger under the different water consumption, sand coarse aggregate ratio. The ultimate bond performance increasing with the concrete strength grade,and it could be reduced the initial slip of steel bar. Added steel fibers of mechanical and adhesive properties of concrete specimens will be reduced as a lightweight aggregate cylinder pressure is reduced.

Key words: HPP fiber lightweight aggregate;mechanical property;bond strength
