摘要
在煤矸石混凝土钢筋拔出试验研究的基础上,探讨了钢筋与煤矸石混凝土的粘结破坏形态。综合分析了煤矸石混凝土立方体强度、保护层厚度、钢筋直径、锚固长度对粘结应力的影响,并与普通钢筋混凝土的粘结性能作了比较。
The failure forms of bond between steel and gangue concrete are examined based on the pullout test. The authors analyse the effects of compressive strengths of gangue concrete cube, lengths of anchorage, thicknesses of coverand diameters of steel on bond stress. The bond characteristics of gangue concrete are also compared with that of common concrete.
