Strength Characteristics of Rice Husk and Corn Cob Ash Blended Cement Concrete

The study investigates the mechanical properties of concrete incorporating Rice husk Ash (RHA) and Concorb (CCA) as cementitious binders. Concrete cubes was prepared from a standardized prescribed mix 1:2:4. cement component in reference replaced with combined % weight rice ash corncob ash. physical chemical composition RHA CCA were examined well workability compressive strength varying percentage blended concrete. Water–cement ratios 0.6, adopted for mixes. A total 75 different percentages by combination to Portland order 0%, 10%, 20%, 30%, 40% cast. measurements performed at ages 7, 14, 21, 28 56 days. results revealed that increased increase curing age but decreased contents increased. lower early stages improves significantly up highest 22.94N/mm2 26.27N/mm2 days 0% 10% respectivelyBased on test concluded content is adequate supplementary material
