Static and dynamic behaviour of recycled tyre rubber-filled concrete
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.
