Investigation of Compressive Strength of Rubberized Concrete Improvised with Silica Fume

Abstract

The disposal of waste tyres has become a major environmental issue due to the massive volume produced globally. Due to the economic and environmental benefits, it appears that recycling discarded tyres was the most effective way of disposing of these materials. This investigation was carried out to find the compression strength of rubberized concrete improvised with silica fume. The percentage of crumb rubber that has been used in the investigation was 0%, 10% and 15%, with 4% of silica fume. The result from experiment shows that as the proportion of the crumb rubber increases, the compressive strength of rubberized concrete samples is decrease. However, the compressive strength is improved with additional of silica fume as replacement of cement. It can be concluded that the rubberized concrete with silica fume able to produce comparative strength as good as conventional concrete.
