钢纤维再生混凝土力学性能的试验研究

Experimental study of steel fiber reinforced regenerated concrete's mechanical properties

对两种不同的钢纤维混凝土和相应的素混凝土进行了抗压、劈裂和4点弯曲试验,结果表明,钢纤维的加入显著地提高了混凝土的劈裂和4点弯曲强度,但抗压强度提高不大;而钢纤维再生混凝土得到的上述强度明显优于钢纤维卵石混凝土。

Two different steel fiber reinforced concretes and corresponding plain concretes are tested for compression, splitting and 4 point bending. The results show that the addition of steel fiber significantly improves the splitting and 4 point bending strengths, but the compressive strength increases a little, and the above strengths of steel fiber reinforced regenerated concrete have the advantage over those of steel fiber reinforced boulder concrete.
