Effect of Hydrochloric Acid on the Compressive Strength of Cement-Cassava Peel Ash Concrete
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 9
Abstract
This research was conducted to investigate the effect of hydrochloric acid on the compressive strength of concrete containing cassava peel ash (CPA). CPA was used to partially replace Portland cement by 0, 5, 10 and 15% by weight of binder in order to prepare CPA concrete. Water to binder ratio was 0.4 and Conplast SP 430 superplasticizer was added to improve workability. CPA concrete was cured for 7 days and thereafter immersed in 10% hydrochloric acid solution for 28 days. All the concrete cubes experienced loss in weight due to leaching with the control concrete recording the least loss.The concrete cubes removed from the HCl acid solution as well the as the ones cured exclusively in water were subjected to compression tests.The loss in compressive strengths of 0, 5, 10 and 15% CPA concrete cubes immersed in 10% HCl solution were 55.7%, 45.9%, 40.8% and 15.2% respectively compared to the concrete cubes cured in water. It is recommended that finer size ash be investigated for possible better results.
