EFFECT OF CERAMIC POWDER WASTE ON THE PROPERTIES OF FRESH AND HARDENED CONCRETE

Abstract

In this study, concrete mixtures weretested to experimental the effect of ceramic powder waste and acacia tortilies gum and evaluate their efficiency on fresh and hardened concrete to achieve the design compressive strengths of concrete [20N/mm2].By using differentceramic waste powder proportions is 5%, 10%, 20% and 30% and 0.5% of acacia tortilies gum from the weight of cement respectively. The study was carried out for 13 types of concrete mixes designed by British Standard,and compressive strength of concrete was measured in the reconstruction of maturing for 7, 28 and 56 days, One of those concrete mixes is a control mix in order to determine the optimum ratio can be added to concrete to obtain design compressive and increase with time. All the results were compared with the normal conventional control mix. The study shown the effect of ceramic waste and acacia gum on workability of fresh concrete by decreasing with the proportion of ceramic waste increase,but for the hardened concrete the specific compressive strength not less than [20N/mm2]up to 30 % of the ceramic waste powder from cement weight at age of 28days.
