The alkalinity of concrete is one of the factors that make it susceptible to acid corrosion. The concrete is corroded through pores by the acid solution, which firstly reacts with the hydration products including calcium hydroxide (CH) and cement paste, resulting in the decomposition of the above products and the damage of mechanical properties [8].
