It was found that at low injection rate the tensile specimen has the best performance for both tensile strength and impact toughness; at low melt temperature, although the tensile properties of the sample is better, but its impact toughness is reduced.
研究发现,低注射速率条件下试样有最优的拉伸性能与冲击韧性;低熔体温度条件下的试样虽然拉伸性能较好,但其冲击韧性反而降低。
The results indicate that along with the increase of concrete cover thickness, the maximum corrosion expansion force of concrete specimen increases; stirrups encryption can be reduced the maximum principal tensile stress of specimen surface, thus inhibited or delayed the appearance of corrosive cracks.
结果表明:混凝土所能承受的最大锈胀力随保护层厚度增加而增大;箍筋加密能降低混凝土表面的最大主拉应力,从而有效抑制或延缓混凝土表面锈胀裂缝的产生。
