Abstract

A study is carried out to investigate the characteristics of concrete various level(0~60%) of fly ash. These results indicate that compressive strength of fly ash concrete seems to be slightly higher than that of ordinary concrete between 7 and 28 days, thereafter the strength of fly ash concrete is significantly higher. In fresh properties of the fly ash concrete, the loss of slump and air content with time up to 120 minutes is lower, but the setting time is increased with increasing fly ash content.
