Abstract: Concrete dependent on Portland cement is most generally utilized construction material on the planet, and its generation pursues a pattern of development. About 15% of the all-out concrete creation contains synthetic admixtures, which are chemicals added to concrete, mortar or grout at the moment of blending to change their properties, either in fresh or solidified state. Algae are photosynthetic amphibian plants that use inorganic supplements, for example, nitrogen and phosphorus. Around 71% of the world is encompassed by sea, the marine green growth naturally known as seaweeds are a differing gathering of photoautotrophic living beings of different shapes (filamentous, lace like, or plate like) that contain pigments, for example, chlorophyll, carotenoids, and xanthophyll’s. It controls the substance response of Cement. It maintains a strategic distance from voids and decline porousness of the solid. To study the strength of marine brown algae concrete different percentages (5%, 10% &15%) of algae are added with cement content to determine the Compression strength , Split Tensile strength concrete ,Shrinkage test and Rapid chloride permeability test for M25, M35 & M40grades of concrete. The Slump of the marine algae concrete is increased as the percentage of Wet Marine Brown algae increases and decrease when compared with the conventional concrete and dry marine algae concrete. The concrete compressive strength is decreased with expanding 15 level of the Wet Marine Brown algae replacement to the conventional concrete and dry marine brown algae concrete. The Split Tensile strength was reduced by 15% Wet Marine Brown algae when compared with conventional concrete.
