Abstract

This paper describes the effect of fly ash replacement on seawater resistance of anti-washout underwater concrete, which was replaced cement by fly ash from 0% to 50%. The experimental work was performed to find out the variations of length and weight of specimens, using a chloride acceleration test in 40℃ The results show that the admixture using fly ash on an anti-washout underwater concrete in the sea environment makes it more durable for the attacks of chloride by seawater. Also, the length of specimens of anti-washout underwater concrete, at age 180 days, increased substantially, compared with normal concrete; however, the mixture in which cement was replaced 50% of fly ash shows 93% reduction of the expansion, compared with the normal anti-washout underwater concrete specimen.
