摘　　要：为研究不同掺量的再生骨料对于钢纤维再生混凝土抗压性能的影响,共进行了五组混凝土立方体试块的抗压试验,研究结果表明:钢纤维混凝土与普通混凝土相比,裂缝的数量较多,但是最大裂缝宽度较小;抗压强度有所增加,但增加量不明显。在钢纤维体积率一定的条件下,随着再生骨料掺加量的增加,钢纤维再生混凝土更易出现裂缝,且裂缝较多;但由于钢纤维的影响,其最大裂缝宽度变化不明显。In order to study the effect of different volumetric fraction of recycled aggregate on steel fiber recycled concrete,five sets of concrete cubes compression test have been done. The re- suits indicated that： compared with ordinary concrete, the num- ber of the cracks of steel fiber reinforced concrete is more, and the maximum crack width is smaller; the compressive strength of Steel fiber concrete increases, but the amount of increase is not obvious. Under the conditions of the certain fiber volume ratio, the more the recycled aggregate contained in steel fiber recycled concrete is, the easier the emergence of cracks is, and the more the number of cracks is. However, the maximum crack width did not change significantly due to the impact of steel f＇ther.
