COMPRESSIVE STRENGTH EVALUATION OF CONCRETE: A PARADIGMATIC USE OF WASTE (SAWDUST AND COW DUNG)
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 4, Issue 10
Abstract
This research aims to find out the optimum compressive strength of concrete produced with partial replacement of cement with cow dung and fine aggregates with sawdust. The concrete mix of 1:2:4 was prepared using water/cement ratio of 0.65 with 0%, 2%, 4% and 6%.Sawdust and cow dung were used concurrently as partial replacement for fine aggregates and cement respectively. The specific gravity values of cement, cow dung, stone dust (fine aggregates) and sawdust are 3.13, 1.33, 3.00 and 1.25 respectively. The compressive strength obtained for different percentages of replacement with cow dung and sawdust are; 8.56N/mm2 , 14.11N/mm2 , 17,33N/mm2 ,18.89N/mm2 for 0% replacement, 7.56N/mm2 , 10.89N/mm2 , 14.22N/mm2 , 17.55N/mm2 for 2% replacement, 5.22N/mm2 , 8.72N/mm2 , 12.22N/mm2 , 15.72N/mm2 for 4% replacement and 3.33N/mm2 , 7.08N/mm2 , 10.83N/mm2 , 14.58N/mm2 for 6% replacement at 7,14,21 and 28 days respectively. It was also discovered that as curing age increases, the compressive strength increases and increase in percentage replacement caused a corresponding decrease in the compressive strength. The Compressive strength value obtained were found to conform to the minimum requirement of 17N/mm2 for light weight concrete especially when 2% cement and fine aggregate were replaced with cow dung and sawdust respectively.
