Experimental evaluation on the performance of self compacting concrete containing glass particles under sulfuric acid attack

Abstract

In the recent years, study on the gradual deterioration of concrete under effect of corrosive factors such as acid attacks has been one of the most important research challenges in the concrete technology. On the other hand, in order to achieving the sustainable development, recycled concrete production by using of building and non building wastes, is interest for researchers more than past. So in this experimental study, for assessing the performance of self compacting concrete containing glass particles under sulfuric acid attack, 9 mixtures comprising 0, 5,10,15 and 20% glass particles as fine and coarse aggregates were considered. To determine fresh and hardened behavior, Slump, T50, V-funnel, J-ring, L-box and compressive and flexural strength tests were performed. In addition, in order to specify the durability of concrete samples, after placing them in the corrosive sulfuric acid solution with PH=1.5 for 30 and 60 days, mass loss and compressive and flexural strengths tests were carried out. Results showed that with increasing glass particles, fluidity, passing ability and dispersion of self compacting concrete increased. After 60 days immersion in sulfuric acid solution, compressive strength reduced for all samples. By adding glass particles, durability of self compacting concrete improved significantly compared to the control mix. Mass of all samples decreased after corrosion, which samples containing glass showed better performance in the mass loss compared to the control sample.
