采用不同的纤维率，不同的基体配合比，进行了抗压强度与残余抗压强度的试验研究。实验表明：钢纤维混凝土在承受极限抗压强度后，试件未有较大的破损，外观良好，仅有微裂，能够继续承受极限压力。通过对试验数据的分析，提出了残余支持力及残余抗压强度的新概念，归纳出残余抗压强度的计算公式。证明了钢纤维混凝土在开裂后仍具有相当大的承载力，能继续有效发挥作用。这种优良的力学性能将有效地将钢纤维混凝土应用于抗震抗爆结构工程中。 Using different fiber ratios and different matrix mix ratios, experimental studies on compressive strength and residual compressive strength were conducted. The experiment shows that after the ultimate compressive strength of steel fiber reinforced concrete, the specimen is not damaged, the appearance is good, and only microcracking can continue to withstand the ultimate pressure. Based on the analysis of test data, the new concept of residual support force and residual compressive strength was proposed, and the formula for calculating the residual compressive strength was concluded. It is proved that the steel fiber concrete still has considerable bearing capacity after cracking and can continue to function effectively. This excellent mechanical properties will effectively apply steel fiber reinforced concrete in seismic anti-explosion structural engineering.
