摘要
进行了4根粉煤灰混凝土简支梁、2根普通混凝土简支梁的受弯试验,通过梁在集中荷载作用下纯弯段和剪弯段受力性能的对比,在综合分析试验数据的基础上,了解低品质粉煤灰的掺入对混凝土抗弯、抗剪力学性能的影响.试验结果表明,低品质粉煤灰混凝土和普通混凝土简支梁在抗弯和抗剪的宏观力学性能上没有明显差别.
Four fly ash concrete beams and two normal concrete beams are tested. The aim of the testing is to study the influence of the low quality fly ash concrete on the mechanic behaviors of the simply supported beams. The flexural and shear behaviors of the beams are contradistinguished separately. The testing results indicate that there is no obvious difference in the flexural and shear behaviors between fly ash concrete beams and normal concrete beams.
