Enhancing corrosion resistance and mechanical properties of reinforced concrete beams through nanomaterial incorporation: a comprehensive investigation

ABSTRACT This research delves into the impact of incorporating nanomaterials into reinforced concrete beams on their corrosion resistance and mechanical properties. Various combinations of nanomaterials, such as nanosilica (NS) and nanoclay (NC), are introduced into the cement matrix to examine their effects on fresh and hardened concrete. Testing is conducted on specimens including cubes, prisms, and beams at intervals of 7, 14, and 28 days to assess compressive and flexural strengths. The aim is to ascertain how different percentages of nanomaterial replacements for cement influence the mechanical properties of concrete. The properties comparable to the conventional concrete and 20% of nano silica addition of the concrete. Additionally, the study investigates the corrosion resistance of reinforced concrete beams with nanomaterials. The specimens tested such as rapid chloride permeability testing, half-cell potential testing, and resistivity testing are employed to determine the corrosion resistance of the beams. It is anticipated that certain combinations of nanomaterials will enhance the mechanical properties of the concrete, thereby improving its resistance to corrosion. The findings of this research hold potential for enhancing the durability and longevity of reinforced concrete structures in various applications.
