Utilization of Used Engine Oil as an Admixture in Concrete

A specific scope of study on the used-engine oil in concrete mix is presented in this paper as to improve the knowledge in the field of construction technology.This paper presents a study on the fresh and hardened properties of concrete containing engine oil.As an attempt for reducing the harmful impacts of throwing the used-engine oil (UEO) in the environment on marine, human and underwater lives and agriculture production, this study proposes to adopt such waste material in concrete industry as a chemical admixture.Therefore, an experimental program is proposed initially to investigate the effectiveness of UEO on the various fresh properties of concrete and hardened properties of concrete.Concrete mixes of M25 grade made with different contents of UEO and Superplasticizer will be prepared to understand their effects on fresh properties of concrete, where increase or decrease in workability as slump and compaction factor and Initial setting time will be found out.The performance of concrete containing UEO (0%,0.25%,0.50%,0.75%,1%)and Water Reducing Agent (WRA) as Superplasticizer (0%,0.50%,1%) in its hardened state will then be thoroughly studied, through assessing the various material properties, namely 3,7,28 & 56-days Compressive strength, Tensile strength & Flexural strength of hardened concrete.
