As a method of sulfuric acid resistance of a concrete structure, there is a method of using a sulfuric acid resistant cement-based material using blast furnace slag fine powder and pozzolanic admixture. On the other hand, sulfuric acid resistant cement-based materials are required to have an improved initial strength. Therefore, we examined sulfuric acid resistant cement-based materials using single micron blast furnace slag fine powder and fly ash. By using a single micron blast furnace slag ultrafine powder, the initial strength was improved with equivalent sulfuric acid resistance. Furthermore, the combination of blast furnace slag sand and blast furnace slag ultrafine powder significantly improved the sulfuric acid resistance.
