Main discoveries on geopolymer concrete’s resistance to sulfuric acid.

Published Work	Key Discovery on Geopolymer Concrete’s Resistance to Sulfuric Acid
Abhilash et al. [67]	After submersion in a 2% sulfuric acid solution for 28 days, the geopolymer concrete was tested to have a 33.82 MPa compressive strength, which is 5.72% less than that without the acid exposure.
Valencia-Saavedra et al. [68]	After 28-day submersion in a sulfuric acid solution of 1 molar concentration, the geopolymer concrete was tested to have a 34.34 MPa compressive strength, which is 20% less than that without the acid exposure.
Çevik et al. [69]	After immersion in a 5% sulfuric acid solution for one month, the geopolymer concrete was tested to have a 39.2 MPa compressive strength, which is 19% less than that without the acid exposure.
