摘要
针对C20、C25和C303个强度等级,50%和70%2种取代率,1.0和1.5、2.0kg/m33种纤维掺入量的不同标养混凝土试块进行了抗压强度试验,并分析了各种再生混凝土的抗压强度数据。研究结果表明:随着玄武岩纤维掺入量的增大,再生混凝土的抗压强度会随之增强,对于试验的3个强度等级的混凝土,当纤维掺入量在1.5kg/m3时,混凝土强度可以达到无再生粗骨料普通混凝土的强度。
The compressive strength test was proceeded of different concrete test block. The block contained three strength grade C20, C25 and C30, two replacement ratio 50% and 70% , three fiber content 1.0, 1.5 and 2.0 kg/m^3. And the block was standard cured. The compressive strength data showed that the compressive strength of recycled aggregate concrete was enhanced with the increasing of fiber content. For concrete of the three strength grade, when the fiber content is 1.5kg/m^3 ,the compressive strength was improved to the strength of ordinary con- crete without recycled aggregate.
