Abstract: An experimental and analytical study was conducted to study the partial replacement of sand using Teak Wood Dust in concrete. The substitution of sand by wood waste can relieve the scarcity of raw materials and lighten concrete masonry block weight. Several trial mixes is being prepared with varying amount of Teak wooden powder. For making M30 grade of concrete replacing sand with teak wood dust in proportions of 0 %, 5 %, 10 %, 15 %, 20 %, 25 % and 30 %. The results obtained by varying the percentage of Teak Wood Dust being analyzed and compared with standard concrete and find out the optimum mix. Then its Workability, strength, durability, impact and water absorption test are studied and compared with control mix. The most important properties of concrete are the compressive strength and Tensile strength. Also, increasing the teak wooden dust incorporation caused decreases in unit weights and strength values of mortars with a parallel increase in water absorption values at all ages.
