— Flexural performance of concrete beams reinforced with steel FRP composite bar SFCB was investigated in this paper Eight concrete beams reinforced with different bar types namely one specimen reinforced with steel bars one with fiber reinforced polymer FRP bars and four with SFCBs while the last two with hybrid FRP/steel bars
— Natural sand in the concrete mixes was partially replaced by 5% 10% 15% and 20% Physical properties such as the density the compressive strength the fresh concrete properties the split tension and the impact load capacity are examined The sand used in the experiment was obtained from a local source with a water absorption
WhatsApp
— The relevant standards as shown in Table 1 stipulate that only natural river sand can be used to the important structures of high speed railway such as the prestressed beam sleeper and track reasons lie in the fact that the quality of MS made by traditional technology is poor and the technology of preparing prestressed
