Using Cassava Peelings to Reduce Input Cost of Concrete: A Waste-to-Wealth Initiative in Southwestern Nigeria
Journal Title: Universal Journal of Environmental Research and Technology - Year 2013, Vol 3, Issue 4
Abstract
This work reports the outcome of an experiment using cassava peelings ash (CPA) of varying quantities to supplement cement in concrete work. The design of the experiment used 0, 5, 10, 15, 20, 25 and 30 per cent cassava peeling ash. The concrete was batched with a ratio of 1:2:4. The cubes produced were allowed to cure for 28 days. Compressive strength test was conducted on the samples at interval of 7 days. The result obtained showed that compressive strength of the concrete increased with increase in length of setting, but decreased as the percentage of CPA. However, the strength still remained in the allowable range of workability for concrete in line with the British standard. With concrete mix using 15 – 20 per cent CPA was found to be the most suitable mix considering the strength and safe use of the concrete. It was concluded that this alternative use of cassava peelings will at the long run create supply paucity, attract higher economic value to cassava peelings, increase the economic return of the farmers and improve the environmental management of the study area.
