Effect of Bacillus Subtilis on Corrosion of Steel in Reinforced Cement Concrete
Abstract: Abstract Concrete is one of the most used building materials due to its cost- effectiveness, ease of availability, and versatility. It is the backbone of modern construction, being widely applied in infrastructure, residential, and commercial projects. However, it is particularly vulnerable to crack formation, which significantly reduces its service life. These cracks compromise structural integrity by allowing water ingress, which leads to the corrosion of reinforcing steel, eventually making the …

Comparative Study of Corrosion Inhibition In Carbon Steel Using Non Ionic Surfactants In Acidic Medium
Abstract: The use of surfactants is one of the numerous ways of protecting a metallic surface from electrochemical oxidation or corrosion. The amphiphilic nature of these surfactants leads to the formation of a protective layer on the metallic surface, effectively minimizing the area of contact between the fluids and the metal, thus inhibiting corrosion. Cationic surfactant like CTAB (Cetyltrimethylammonium bromide) has been most commonly used as a corrosion inhibitor, but since …
