本文总结了在静、动荷载作用下，用小体积的轮胎碎橡胶和聚丙烯短纤维填充混凝土试件在7天和28天的力学性能试验结果。并将试验结果与无纤维、无轮胎混凝土试件进行了比较。为了分析水泥-橡胶纤维的相容性，文中还对其界面进行了微观研究。进行了压缩、间接拉伸和弯曲静态试验和压缩动态试验。利用动态试验结果计算了该材料的复模量和低频动力作用下耗散弹性能的能力。(C) 2002 Elsevier Science Ltd.版权所有。
The paper summarises the experimental results of mechanical behaviour under static and dynamic loads of specimens made of concrete filled with small volumetric fractions of crushed tyre rubber and polypropylene short fibres, at 7 and 28 days. The experimental results are compared with results of concrete specimens of similar features without fibres or tyre. The results of a microscopic study (SEM) of the interface cement-rubber fiber are included in order to analyze their compatibility. Compression, indirect tension and bending static tests and compression dynamic tests have been performed. The results of the dynamic tests have been used to calculate the complex modulus and the capacity of this material to dissipate elastic energy due to low-frequency dynamic actions.
