This research deals with the anti-washout underwater concrete applied for cast-in-place piles constructed by RCD(Reverse Circulation Drill). The anti-washout underwater concrete exhibits a compressive strength larger than 35 MPa and a slump flow of 600 mm. It is also a high fluidity anti-washout underwater concrete with an intended mass of suspended solid smaller than 150mg/ℓ. And then, we evaluated the quality performances and the fludity characteristic of the developed high fludity anti-washout underwater concrete in this study.
