With the increase of environmental damage, especially in the Arab region as a result of wars in the past years and the destruction of infrastructure, engineers are concentrating more on reducing adverse environmental influences. In this study, the effect of three types of acids on the concrete properties, the corrosion progresses, chemical reaction rate and the penetration of the acid to the concrete were tested. The types of acids used in this research are Nitric, Sulfuric and Hydrochloric acids. It has been adopted to make holes in concrete cubes before submerging them with acid solutions to determine the penetration and chemical reaction rate by observation, all the solutions where ready to be poured in the holes using 2 cubes of concrete for each of the 8 solution which have different concentrations of acids. The results indicated that the rate of chemical reactions are not the same for the acids which they have different concentrations. The Nitric acid is more corrosive and reactive since the concrete absorbed 100 mL in 330 minutes through a contact area of 23 cm2. Nitric acid have reduced the compression strength by 37% and the mass loss is 21%.
