Sulfuric AcidAttack on OrdinaryPortland Cementand Geopolymer Material. The resistance of ordinary Portlandcement bindertowardsacidhad been widely discussed by researchers. The deterioration effect of this binder may cost highrepairexpense and rehabilitation.
The yellow surface revealed that thesulfuric acid corrosion degreewas serious, and the surface of the concrete specimen had a looseyellow sand layer. The white surface shows that a large amount of CaSO 4 (calcium sulfate) was deposited on the concrete specimen surface.
Asulfuric acid resistant grout compositionaccording to the present invention containscement, and has a number average molecular weight of 2000 to 6000 and a weight average molecular weight of 3000 to 30000 with respect to 100 parts by mass of cement.
Thesulfuric acid resistanceoffly ashbased geopolymer concrete blended with an additional calcium source is presented in this paper. Ordinary Portland cement (OPC) was added as additional calcium in the geopolymer system as flyash replacement(0, 10, 20 & 30%).
