[1220] PERCEPTION OF FLY ASH USAGE IN MONGOLIAN CONCRETE INDUSTRY
キーワード：chemical composition, compressive strength, fly ash concrete, Mongolia
Mongolia has not established a way to utilize fly ash, which is a by-product of burning coal. Consequently, a considerable amount of fly ash is dumped in fly ash disposal ponds in the outer suburbs of Ulaanbaatar. The purpose of this report is to investigate the current situation regarding the use of fly ash concrete in Mongolian concrete companies, and find the major obstacles for promoting fly ash concrete in Mongolia. Additionally, compressive strength tests of concrete made with different types of fly ash and cement were conducted to confirm the rationality of companies' opinions.
