UHPFRC has high potential for various kinds of structural application including repair and reinforcement of existing RC structures. This study is an experimental investigation that aims at providing UHPFRC with anti-washout properties for under-water use. Results showed the modified UHPFRC with 2% of cellulose ether properly satisfied the standard quality values for anti-washout materials (pH value and turbidity). This new material has a compressive strength of above 100 N/mm2 and a tensile strength of 7.69 N/mm2 as well as high flexural toughness (provisionally at 7 weeks age). Both the compressive and tensile constitutive-laws are also presented for structural design.
