The Effects of Fly-ash Replacement on the Properties of Undispersed Underwater Concrete

The purpose of this study is analyze the properties of undispersed concrete according to replacement of the ratio of fly-ash. The test results show that as the ratio of flyash replacement which increasing fluidity but the amounts of air content, suspended solid and pH values dicreased and setting time is delayed. The ten persent replacment of fly-ash has less water pollution and high compressive strength value than other ratio of fly-ash replacement.
