摘　　要：通过试验手段,分析了波浪型钢纤维、端勾型钢纤维和再生微粉掺量变化对砖混骨料全再生混凝土力学性能的影响.结果表明:两种钢纤维可提升砖混骨料全再生混凝的抗压强度、劈裂抗拉强度和轴心抗压强度但影响程度有所不同,而再生微粉却使其三个力学性能均出现明显的下降.This article analyzes the influence of changes in the dosage of wave-shaped steel fiber,hookedend steel fiber,and recycled micro powders on the mechanical properties of fully recycled concrete with brick and concrete aggregates through experimental methods.The results show that two types of steel fibers can improve the compressive strength,splitting tensile strength,and axial compressive strength of fully recycled concrete with brick and concrete aggregates,but the degree of influence is different.However,recycled micro powder causes a significant decrease in all three mechanical properties.
