为揭示玻璃混凝土与钢筋的粘结锚固规律,采用中心拉拔试验方法,研究分别使用粗玻璃和细玻璃取代混凝土中粗骨料和细骨料对混凝土与钢筋的粘结强度的影响.试验结果表明:废弃玻璃粗骨料混凝土试件与普通骨料混凝土试件的极限粘结强度相当;废弃玻璃细骨料混凝土试件的极限粘结应力较普通混凝土试件的极限粘结应力有很大的提高;废弃玻璃骨料钢筋混凝土具有较好的锚固延性;废弃玻璃细骨料混凝土试件中,钢筋与混凝土达到极限粘结应力时发生的相对滑移与普通骨料混凝土相近;废弃玻璃粗骨料混凝土试件中,钢筋与混凝土达到极限粘结应力时发生的相对滑移大于普通骨料混凝土.
In order to reveal the bonding and anchoring rule of glass reinforced concrete and reinforced concrete, center drawing test was used to study the effect of using coarse glass and fine glass instead of coarse aggregate and fine aggregate on the bond strength of concrete and steel bar respectively. The results show that the ultimate bond strength of waste glass coarse aggregate concrete specimens is similar to that of ordinary aggregate concrete specimens. The ultimate bond stress of waste glass fine aggregate concrete specimens is larger than that of ordinary concrete specimens The relative slip between rebar and concrete reached the ultimate bond stress was similar to that of common aggregate concrete. The waste glass coarse aggregate had the better anchorage ductility. In abandoned glass fine aggregate concrete specimen, Aggregate concrete specimens, steel and concrete to achieve the ultimate bond stress occurs when the relative slip greater than ordinary aggregate concrete.
