【摘要】：用油菜秸稈灰分等量替代5%、10%、15%的水泥,分別制作強(qiáng)度為C20、C30、C40的秸稈灰分混凝土試件,測試混凝土的粘結(jié)強(qiáng)度,考察月牙紋鋼筋與油菜秸稈灰分混凝土的粘結(jié)性能。結(jié)果表明,油菜秸稈灰分摻量為5%時,3個強(qiáng)度下的油菜秸稈灰分混凝土與月牙紋鋼筋的粘結(jié)強(qiáng)度分別為19.06、19.90、20.08 MPa,與普通混凝土相當(dāng),油菜秸稈灰分摻量10%和15%的混凝土與月牙紋鋼筋粘結(jié)性能較普通混凝土減弱。改變5%摻量油菜秸稈灰分混凝土植入鋼筋的類型與月牙紋鋼筋直徑,月牙紋鋼筋與油菜秸稈灰分混凝土的粘結(jié)強(qiáng)度是光圓鋼筋的2.55倍;月牙紋鋼筋直徑從12 mm增至16、20 mm,粘結(jié)強(qiáng)度分別下降了6%與25%,油菜秸稈灰分混凝土粘結(jié)性能隨著月牙紋鋼筋直徑增加而減弱。
[Abstract]:The straw ash concrete specimens with C20C30C40 strength were made with the same amount of rape straw ash instead of 510% cement. The bond strength of the concrete was tested, and the bond properties between crescent grain reinforced bar and rape straw ash concrete were investigated. The results showed that when the ash content of rape straw was 5, the bond strength between rape straw ash concrete and crescent reinforcement was 19.06 ~ 19.90 ~ 20.08 MPa, which was similar to that of ordinary concrete. The bond property between the concrete with 10% and 15% ash content of rape straw and crescent reinforcement is weaker than that of ordinary concrete. The bond strength between crescent steel bar and rape straw ash concrete is 2.55 times of that of smooth steel bar by changing the type of reinforcing bar and the diameter of crescent steel bar when the content of rape straw ash concrete is 5%, and the bond strength between crescent grain reinforced bar and rape straw ash concrete is 2.55 times. The diameter of crescent steel bar increased from 12 mm to 16 mm, and the bond strength decreased by 6% and 25%, respectively. The bond property of rape straw ash concrete decreased with the increase of the diameter of crescent steel bar.
