A　new　artificial　reef　concrete　(NARC)　with　sulphoaluminate　cement,　marine　sand　and　sea　water　et　al.　was　proposed.　The　effect　of　cement　type,　sand　type　and　water　type　on　the　workability　(namely　slump,　slump　loss　cohesiveness,　water　retention),　mechanical　properties　namely　compressive　strength,　splitting　tensile　strength　and　dynamic　elastic　modulus)　and　affinity　(namely　surface　initial　pH　value　and　the　leaching　rate　of　alkaline　material　in　concrete)　of　concrete　was　studied.　The　microstructure　of　concrete　was　detected　by　X-ray　diffraction,　scanning　electron　microscope　and　pore　structure　analyzer,　respectively.　The　studies　show　that　NARC　has　superior　workability,　mechanical　properties　and　affinity　compared　to　ordinary　Portland　cement　concrete　with　river　sand　and　fresh　water.　Therefore,　the　feasibility　of　NARC　in　artificial　reef　is　verified.　(C)　2015　Published　by　Elsevier　Ltd.
