Abstract: The objective of this research is to explore the effect of sawdust as an admixture in concrete as well as that of sodium chloride solution as a curing medium of concrete. Most of the constructions in nearby sea areas utilize the sea water for curing concrete which contains a considerable amount of sodium chloride and also utilizing sawdust waste will be of great advantage due to the high rising cost of conventional building materials. The results show that the slump value of the concrete mix reduces as the amount of the sawdust (admixture) increases. also there is progressive loss of compressive strength of cubes cured in 5% sodium chloride having concentration of 50,000PPT with increase in sawdust content of 0%, 5%, 10% and 15% ranged 17.56 N/mm2 to 16.22 N/mm2 at 7days, 22.27N/mm2 to 16.92 N/mm2 at 14days, 22.77 N/mm2 to 20.09 N/mm2 at 21days and 24.34 N/mm2 to 21.45 N/mm2 at 28days respectively. The results show that Sodium Chloride has the properties of impurity reducing the strength of concrete and sawdust is not suitable to be used as admixture because it shows a progressive decrease in the compressive strength of concrete with a corresponding increase in its content.
