Acid-Resistant Concrete. Does a mix containing fly ash have resistance to sulfuric acid Not directly. A wet surface of ordinary concrete exposed to hydrogen sulfide is rapidly attacked because of the evolution of sulfuric acid. Tests have shown that this effect can be almost entirely avoided if the mix contains a proportion of fly ash.

Prognosis Of Concrete Corrosion Due To Acid Attack
The corrosion resistance of concrete with quartzitic acid-resistant aggregate depends on the chemical composition of the cement. According to De Belie et al. (1996) the vulnerability of concrete to attack by lactic and acetic acid decreases over the groups Portland cement without C Note that the aggression of the acid attack is not only because of its pH value but also due to the presence of CO 2 in relation with the hardness of water.. Effect of Sulphuric Acid on Concrete Sulphuric acid attack causes extensive formation of gypsum in the regions close to the surfaces and tends to cause disintegration and mechanical stresses which ultimately lead to spalling and
