• Enhancement of strength and durability of fly ash concrete in seawater environments: Synergistic effect of nanoparticles
• Fly ash is used in concrete industry to reduce the amount of cement and to enhance the durability of concrete. Nuclear industry recently adopted fly ash concrete as a government initiative to reduce carbon footprint and also to provide an impermeable skin for the several structures in the cooling water system exposed to marine environment for enhanced durability. Earlier detailed studies on fly ash concrete have shown that despite its superiority over conventional concrete with respect to strength and durability, some concerns such as delayed setting and hydration, low early-age strength, and higher carbonation may pose a problem for its wider application. The present work is an attempt to overcome these deficiencies by nanophase modification of concrete with the incorporation of nano-titania (NT) and nano-calcium carbonate (NC) at 2% by weight of cement separately and in combination. The synergy of 1% NC and 1% NT emerged superior with excellent concrete properties, durability and antibacterial activity.
• Biodeterioration resistance of nanophase modified fly ash concrete specimens: Accelerated studies in acid producing microbial cultures
• This work investigates the effect of an acid producing fungus and anaerobic sulfate reducing bacteria (SRB) on nanophase modified fly ash (FA) concrete specimens. Four different types of concrete specimens namely FA (FA concrete with 40 wt % replacement of Ordinary Portland Cement), FAT (FA concrete modified with 2 wt % TiO2), FAC (FA concrete modified with 2 wt % CaCO3), and FATC (FA concrete modified with 2 wt % TiO2:CaCO3) were fabricated. These specimens were exposed to microbial cultures for accelerated biodeterioration studies. Growth of microbes on specimen surfaces was visualized by epifluorescence microscopic studies. Important biodeterioration parameters like pH reduction, weight loss, thickness, and diameter loss under biofilms were analyzed. Absence of degradation phases like ettringite and calcium oxalate in the modified FA concrete was confirmed using X-ray diffraction studies. Results proved biodeterioration resistance of all the three-nanophase modified FA concrete specimens. Among the three, FAT emerged superior with excellent resistance to biodeterioration owing to the presence of TiO2 nanoparticles.
• Seawater corrosion resistance of reinforcement in nanophase modified fly ash concrete
• A combination of natural and accelerated corrosion tests were performed to evaluate the corrosion resistance of reinforcements. The tests were conducted on four types of fly ash concrete specimens with and without nanoparticles designated as fly ash concrete with 40 wt% fly ash (FA), fly ash concrete with 2 wt% nano-CaCO3 (FAC), fly ash concrete with 2 wt% nano-TiO2 (FAT) and fly ash concrete with 1 wt% nano- CaCO3 and 1 wt% nano-TiO2 (FATC). Electrochemical measurements showed that reinforcements in nano-CaCO3 modified fly ash concrete (FAC) exhibited noble potential value, high polarization resistance and lower corrosion rate. Impressed voltage test also corroborates the enhanced corrosion resistance of FAC specimens, which was evident from the longer crack initiation time with minimum anodic current as compared to fly ash concrete without nano additives. Corrosion products of cover concrete showed a comparatively lesser amount of detrimental phases like lepidocrocite and goethite which was in agreement with the corrosion results. The least depth of chloride ion penetration indicated the effective plugging of pores by nano-CaCO3 particles that prevent diffusion and movement of chloride ions to surface of the rebar and thereby maintaining the passivity of the thin iron oxide layer around the steel rebar.
