Through　biogenic　sulfuric　acid　attack　on　concrete,　comparisons　between　ordinary　Portland　cement　concrete　(OPCC)　and　new　artificial　reef　concrete　(NARC)　prepared　with　sulphoaluminate　cement,　marine　sand　and　sea　water　were　made.　Biogenic　sulfuric　acid　corrosion　resistance　was　studied　by　analyzing　the　surface　and　localized　morphology,　mass　loss　and　compressive　strength　of　both　concrete　specimens.　The　corrosion　products　were　investigated　by　environmental　scanning　electron　microscope　(ESEM),　X-ray　diffraction　(XRD)　and　Fourier-transform　infrared　(FT-IR).　Results　showed　that　the　visually　apparent　corrosion　degree　and　loss　rates　of　mass　and　compressive　strength　are　higher　for　OPCC　than　for　NARC　following　exposure　to　biogenic　sulfuric　acid.　©　2017　Elsevier　Ltd
