Abstract：In this paper, the effects of two optimal underwater anti-washout admixtures which werepolypropylene-type PVAD and cellulose-type HPMC on the fresh concrete properties, fluidity and self-compacting degree of concrete made with the technique of single addition and mixed addition respec-tively were studied. And the effects of the addition of them on the anti-washout resistance and strengthof underwater concrete which was cast by tremie method were studied. The results indicate that theanti-washout resistance and strength of underwater concrete prepared with the technique of mixed ad-dition is better than those of underwater concrete with the technique of single addition.
