Preparation of nanocomposite concrete improved with modified rubberpowder

In this paper, unmodified rubber powder was treated with hydrogen peroxide to produce hydrogenperoxide-activated rubber powder (HRP). Subsequently, silica nanoparticles were added to theconcrete, followed by incorporating the modified rubber powder into the concrete mixture. Fouriertransforminfrared spectroscopy (FTIR) was used to analyze the modified rubber powder. Concretesamples were tested for compressive strength after ۲۸ days of water immersion. The resultsdemonstrated that functional groups introduced during modification improved the interactionbetween rubber and concrete. Additionally, compressive strength analysis showed that samplescontaining modified rubber powder with silica nanoparticles exhibited superior compressive strengthcompared to those containing unmodified rubber powder
