Effects of some chemical detergents additions on concrete

Usually, the drainage network made of concrete and which fall under the infrastructure in cities. This research aims to study the corrosion of cement concrete under the influence of Washing Detergents, as well as determine the negative influence on some properties such as weight and mechanical resistance. The results showed that sodium phosphate salts by 27-35% of the weight of the detergent has led to weaken the resistance of the pressure of the cement mortar by 5%, and sodium sulphate salts and sodium chloride led to weaken on pressure resistance and inflexion by 15%. Corrosion Index showe proposed sharp decline very resistant to detour - the pressure resistance by up to 30%. Keywords: Concrete. Detergent. Corrosion. Resistance. Mechanical resistance, Weight. Index
