Abstract
The aim of this work is to improve the fresh and hardened concrete properties made from recycled
concrete aggregate, by using a non-traditional admixture.As the previous researches concluded,
using different ratios of recycled concrete aggregate has a harmful effect on the properties of fresh
and hardened concrete. Otherwise, itpresents a cheap, environmental and sustainable concrete by
using the waste materials of demolitions to replace the natural aggregate in concrete mixes.
Therefore, organic non-traditional admixture is used in this study to improve fresh and hardened
concrete properties.The admixture was prepared using a cheap local material mainly from wastes of
vegetable oil industries.Six different types of admixtures were prepared to select the best and most
homogenous one.The suggested admixture gives best workability and increase thecompressive
strengthof concrete mixescontaining recycled concrete aggregate.
