Description The strength performance of the concrete structures is of great importance in the field of Civil Engineering. Concrete is the most prevalent and an artificially made construction material all over the world. Concrete is used for the construction of bridges, dams, abutments, and many other hydraulic structures. These structures remain in seawater throughout their service life. As seawater contains a lot of salts, composed of chlorides and sulphates and many other reactive elements. These chloride and sulphates attack on the concrete and cause deterioration of structure. Therefore, the aim of this study was to investigate the strength performance of concrete containing Date Seeds (DS) exposed to Sodium Chloride (NaCl) and Sodium Sulphate Na2SO4. In this study we have replaced the Coarse Aggregates with Date Seeds (DS) by different percentages of weight i.e. (CA:DS)%, (100:0)%, (98:2)%, (97:3)% and (96:4)%. The constant water cement ratio was used in all mixes i.e. 0.5. Workability, Density, and compressive strength were examined by casting 48 standard cubes of 100mm size, and exposure to the NaCl and Na2SO4 Solution for curing at 7 and 28 days. Test results demonstrated that workability first increase at 2% replacement but then decreases as replacement increases. The results of Density and Compressive Strength of Cubes cured in plain water and in mixed solution of NaCl and Na2SO4 were compared. It was observed that the replacement of coarse aggregate with date seeds was increases workability of concrete. Density and compressive strength of cubes cured in plain water decreases to a small extent. For Compressive Strength, it was observed at 28 days, that the Compressive Strength of cubes placed in normal water for curing have greater values as compare to the cubes placed in the salt solution.
