The present paper aims to find the strength and durability properties of hybrid fiber reinforced concrete under marine conditions, and to investigate the effect of hybridization of fibres on properties of concrete. where the fibers to be used are steel fiber and polypropylene fiber and to find the proper corrosion less hybrid fiber reinforced concrete by adding the chemical admixture i.e CHYRSCO OPTIMA 9313 and MICRO SILICA to produce a moderate water reduction, better flow and retention of HYRC. Water to cement ratio increases there is a chance of high extend of having concrete permiablity, so in this investigation water to cement ratio is about 0.38 % only. The literature study reveals that there is very little literature on the durability aspects of marine conditions on hybrid fibers reinforced concrete hence lot of research is to be done. Present experimental investigation is done up to M40 grade concrete mix design. The compressive strength is one of the most important features of concrete,Compressive strength was investigated, the mix design also affected the water-cement ratio The planned technique allows the designer to estimate characteristics such as compressive strength and workability of the concrete
