PERFORMANCE OF COW DUNG POWDER ON COMPRESSIVE STRENGTH OF BLENDED CONCRETE
Journal Title: World Journal of Engineering Research and Technology - Year 2018, Vol 4, Issue 3
Abstract
This research work aims at using cow dung powder (CDP) as partial replacement for cement in concrete production. The percentage replacements were varied from 0%, 5%, 10%, 15%, 20%, 25% and 30% with water cement ratio varied from 0.54, 0.57, 0.60, 0.64, 0.68, 0.72 and 0.77. The mixing ratio was 1:2:4. The result of chemical analysis conducted on cow dung powder shows that it is pozzolanic. The Workability result gives 20mm, 15mm, 15mm, 13mm, 11mm, 9mm, and 8mm for CDP with 0%, 5%, 10%, 15%, 20%, 25% and 30% replacements. Concrete cubes of size 150 x 150 x 150mm were cast, cured and tested at different maturing ages of 7, 14, 28, 56 and 112 days. The compressive strength results for 0%, 5%, 10%, 15%, 20%, 25% and 30% replacement for CDP varied from 15.12-32.44, 12.02-26.64, 8.72-22.48, 6.12-20.26, 5.09-18.03, 4.81-15.03, and 4.67-14.36 (N/mm2) respectively. The 20% replacement meets strength requirement (17N/mm2) for light weight concrete.
