摘要
研究了钢筋直径对粉煤灰混凝土与钢筋粘结性能的影响.结果表明:钢筋与粉煤灰混凝土的粘结性能随着钢筋直径的减小而加强;同一外荷载作用下,钢筋直径为18mm的试件钢筋应变值比钢筋直径为22mm的试件大;钢筋直径为18mm的试件应力峰值的漂移更明显.
Influence of reinforcing steel diameter on adhesion performance of fly ash concrete is conducted and the findings show adhesion performance will be strengthened as the diameter decreases.Under the same external load,the value with diameter 18mm is larger that that with diameter 22mm.The drift of stress maximum of the former is more obvious.
