Experimental Study on Concrete Incorporating Date Seed As Partial Replacement Of Coarse Aggregates

In the world the most widely used material is concrete. It is the most important and second number consumable substance after water in the world and plays a vital role in infrastructure and private buildings construction. Various waste materials like coconut shells, date seeds, rubber seed shell, palm kernel shells, etc. were studied by various researchers and replaced for coarse aggregate in concrete making. This study attempted to use Date Seeds as a fractional replacement with coarse aggregate in the concrete. The design mix ratio 1:2:4 of binding substance cement, fine aggregate and coarse aggregate/date seeds were investigated in this study work only. Total 24 number of Cylinders of diameter and height of 4’×8’ were made. The 0%, 2%, 3% and 4% of Date Seed were replaced with Coarse aggregate. The physical properties of Date Seed, fine aggregate and coarse aggregate were find out. The specific gravity of DS was calculated 1.0 and water absorption was 24% for 48 hours. The bulk density value was 843 kg/m 3 which was greater than the previous research works, the fineness modulus of DS, CA & FA were 1.7, 2.18 and 3.08, respectively. Another important thing which was observed during this work that the DS ws expanding on the absorption of water. The workability of concrete was decreasing as the total surface area of coarser particles was increased. The results of compressive strengths were quite satisfied at 2% & 3% replacement.
