Evaluation on Sulfuric Acid Resistance of Concrete Protected by Biomimetic Coating Mortar

Article Preview

Abstract:

The objective of this study is to evaluate the sulfuric acid resistance of the concrete coated with bacterial-glycocalix-based biomimetic coating mortar. The variation of the compressive strength and mass of the coated concrete since the specimen was immersed into an aqueous solution of 5 % sulfuric acid were 0.88 and 12 % at the age of 56 days, respectively, showing a superior deterioration resistance. As a result, it can be concluded that the developed biomimetic coating mortar possesses a great potential for enhancing the deterioration resistance performance of concrete.
