STRENGTH BEHAVIOR OF CONCRETE USING POMEGRANATE PEEL ADMIXTURE

Abstract

The classical chemical additives to the concrete are considered one of the important factors for improving the properties of concrete in structural designs. On another hand, due to the proliferation of wastes resulting from foodstuff, which is deemed as one of the important reasons for environmental pollution, and due to the interest of global studies to reduce the quantities by recycling or using them to produce beneficial substances, so this study deals with studying the possibility of utilizing from pomegranate peel residue as an admixture to Ordinary Portland Cement (OPC) and study the effect of these peels on the behavior and the properties of concrete. The chemically-treated pomegranate peels were used as an additive substance to investigate the behavior, mechanical properties of fresh and solid concrete. The admixture ratio of (pomegranate shell/cement) was ranging between 0-0.7% by weight with a mix proportion of (1:2:4) (cement:sand: gravel) by volume and the same water to cement ratio (W/C) of 0.45. The experimental tests show that increasing in concrete compressive strength, splitting tensile strength, flexural tensile strength, and modulus of elasticity by 25.94%, 8, 21.05%, and 11.10 respectively with an increasing the ratio of pomegranate peel additives to a certain percentage. Thus, the pomegranate peel deems to be a good and non-cost concrete admixture.
