Application of concrete for pavement and barrier purposes demands ample energy absorption capacity and impact resistance characteristics. These attributes were investigated for concrete produced by using waste plastic shredded fibers (WPSF), which were obtained by shredding waste plastic bags. The WPSF were incorporated in concrete at an amount of 0, 0.5, 1.0, 2.0, 3.0, and 5.0% by weight of concrete. The strength (compressive and impact), and the ability to absorb the energy of concrete samples incorporating WPSF were evaluated. Additionally, empirical relations were also developed between WPSF fraction and compressive strength; WPSF fraction and impact energy for the first crack; WPSF fraction and impact energy for final failure; and WPSF fraction and energy absorption capacity using regression analysis method. The outcomes of the tests showed that there was a systematic decline in compressive strength of concrete on the inclusion of WPSF. However, superior energy absorption capacity and higher resistance to impact of concrete specimens were observed on the inclusion of WPSF. It was thus concluded that WPSF could be incorporated in concrete up to certain level for producing sustainable concrete pavement and barrier.

含废塑料切碎纤维的混凝土的评估：延展性

将混凝土用于路面和屏障的应用需要足够的能量吸收能力和抗冲击特性。对于使用废塑料切碎纤维（WPSF）生产的混凝土，研究了这些属性，这些废塑料切碎纤维是通过切碎废塑料袋获得的。将WPSF以混凝土的0、0.5、1.0、2.0、3.0和5.0重量％的量掺入混凝土中。评估了掺入WPSF的混凝土样品的强度（抗压强度和冲击强度）以及吸收能量的能力。另外，WPSF分数与抗压强度之间也建立了经验关系。WPSF分数和第一个裂纹的冲击能；WPSF分数和最终失败的冲击能量；WPSF分数和能量吸收能力采用回归分析方法。测试结果表明，加入WPSF后，混凝土的抗压强度有系统的下降。但是，在加入WPSF后，观察到了卓越的能量吸收能力和更高的抗混凝土试样冲击能力。因此得出结论，可将WPSF掺入混凝土中达到一定水平，以生产可持续的混凝土路面和障碍物。
