Ready mix concrete plant waste aggregate concrete (R.M.C.A.C) is concrete in which some or all of the high-quality aggregates is from waste aggregate. two In this study, the consequences of various nitric acid concentrations (0%, 5%, 10%, 15%, and 20%), diagram mix, publicity length (28, 56, and 84 days) and proportion waste aggregate concrete. two (R.M.C.A.C) content (0%, 25%, and 50%) on the compressive energy of Ready mix concrete plant waste aggregate concrete. two (R.M.C.A.C) were investigated. The assessments have been carried two out with a view two to two simulating the performance of Ready combine concrete plant waste combination concrete. (R.M.C.A.C) in contact with soluble nitrate-based substances. 150x150x150mm cubes of Ready mix concrete plant waste aggregate concrete. (R.M.C.A.C) were solid and moist-cured for 28 days and the strength of concrete at this age was determined. The cubes had been thereafter immersed in 0%, 5%, 10%, 15%, and 20% concentrations of nitric acid for a whole of 84 days. Compressive electricity tests have been carried out at the stop of 28 days, 56 days and 84 days of immersion. The results of the exams indicated that the compressive strength notably reduces with make bigger in acid concentration, immersion period and waste combination concrete. two (R.M.C.A.C) content. The effect of richness of mix on resistance of Ready combine concrete plant waste aggregate concrete. two (R.M.C.A.C) to the acidic aggression will become extra mentioned at the absolute best (50%) waste aggregate concrete. Two(R.M.C.A.C)content. Keyword: compressive strength, Ready mix concrete plant waste aggregate concrete. (R.M.C.A.C), nitric acid concentrations, percentage waste aggregate concrete content. © IAEME Publication
