Is it possible to dissolve concrete with acid - Stack Exchange

2019-6-27  Concrete is frequently treated with dilute hydrochloric acid to etch the surface prior to painting or coating with epoxy. After treatment with acid, good rinsing is suggested. This etch treatment will react with CaCO3 at the surface (Ca(OH)2 produced as a product of the hydration of cement reacts with CO2 in the air to form CaCO3 over a period ...

What type of reaction is CaCO3 2HCl? –

2020-4-1  Calcium carbonate is not very soluble in water. This is an acid-base reaction (neutralization): CaCO3 is a base, HCl is an acid. What is the chemical equation for CaCO3 and HCl? So the equation of the reaction between calcium carbonate and HCl is: CaCO3+2HCl =CaCl2+H2O+CO2. What happens when HCl reacts with CaCO3?
