In order to study impact mechanical properties of the basalt fiber reinforced concrete, the BFRC specimens with 0、0.1% and 0.3% fibre volume content were prepared. The Φ100mm split hopkinson pressure bar apparatus was adopted tocarry out the impact compressive experiment. The dynamic stress-strain curves were obtained. The impact mechanics performance of BFRC were studied through analyzing the impact compressure strength and deformation.
摘 要：为了研究玄武岩纤维混凝土（basalt fiber reinforced concrete，简称BFRC）的冲击力学性能，制备了纤维体积掺量分别为0、0.1%和0.3%的BFRC试件，采用Φ100mm分离式霍普金森压杆（split hopkinson pressure bar，简称SHPB ）设备对BFRC试件进行了冲击压缩试验，得到了BFRC的动态应力应变曲线，从冲击压缩强度和变形两方面研究了不同应变率下BFRC的冲击力学性能。

Under the same situation as steel tube ratio and volumetric percentage of stirrups and so on, yield load and increases with the increasing of reinforced bar-diameter. But the variety of reinforced bar-diameter has ruleless to limited load and ductibility.
4在含钢率、配箍率等其他属性相同的情况下，屈服荷载随着钢筋直径的增大而增大，但钢筋直径的改变对极限荷载和柱的延性的改变不具有规律性。

The results show that BS 460MPa grade reinforced bar can be produced all from Q235 or 20MnSi billet by the remained heat treatment process but the production cost of the former is lower. When the water pressure minishes, the intensities of reinforced bar reduce; the higher the temperature at the entrance of cooling bed is, the lower the intensities are. Therefore, the commendatory process parameters are that five stages coolers should be opened, water pressure should be all 1.8～2.0MPa and the temperature at the entrance of cooling bed of Q235 reinforced bar should lower than 650℃. The typical microstructure(Q235): the surface layer is tempered sorbite; the transition layer is pearlite and ferrite, and the partial ferrite is acicular; the core is pearlite and ferrite and the grain fineness is 8～10 grade. The yield strength is reduced by 10～20MPa after natural ageing and it can be simulated by artificial ageing(100℃×2h or 200℃×1h).
结果表明，Q235和20MnSi钢都可以利用余热处理工艺生产出性能合格的钢筋，但前者的生产成本较低；水压减小，钢筋强度降低，上冷床温度越高，强度越低，推荐5段水冷器全开，水压均为1.8～2.0MPa，Q235钢筋的上冷床温度应控制在650℃以下；钢筋典型的金相组织（Q235）表层为回火索氏体，过渡层为珠光体+铁素体且部分铁素体呈针状，心部为珠光体+铁素体，晶粒度8～10级；自然时效后屈服强度下降10～20MPa，用人工时效可以模拟自然时效，工艺是100℃×2h或200℃×1h。
