Literature review on steel fibre, silica fume and fly ash: improving methods for recycled and multiple recycled aggregate concretes

If all concrete is to be recycled in a future scenario, will needed. Usually recycling causes loss of properties, but this does not have truth for the mixtures. This paper shows comprehensive knowledge about improving methods used keep properties aggregate (RAC). In reviewed literature several kinds RAC were tested with various replacement ratios. The effect adding steel fibres, silica fume or fly ash mixture also examined both separately and together. Most experiments demonstrated excellent mechanical compared ordinary concretes. Based on these results ideal composition can deduced imagined when multiple times (MRAC).
