Abstract
This paper presents results from an investigation on the potential use of waste vulcanized rubber scrap (WRS) particles as aggregate in construction mortars. The investigation was carried out using a 32 factorial design of experiments and the response surface methodology. Mortar mixtures were prepared using WRS as fine aggregate (10, 20 and 30 vol.%) with water/cement ratios of 0.52, 0.55 and 0.60. Fresh mortar consistency index and hardened mortar 28-day compressive strength were evaluated. The influence of the WRS content on the physical and mechanical properties was established, and the suitability of WRS use in a mortar application was demonstrated.
