ABSTRACT:

Cement, aggregate, and water are used to create concrete structures. More difficult than at any other moment in recent memory, the building industries are proving to be. The engineering sector associated with the industries needs a chance to succeed in order to remain competitive. The usage of materials for building purposes is one of the areas that can be developed. In order to advance knowledge in the field of construction technology, this paper presents a special scope of investigation on engine oil in the concrete mix. The investigation of the characteristics of freshly-poured and fully-cured motor oil-containing concrete is presented in this work. In an effort to lessen the negative effects that disposing of used engine oil (UEO) in the environment has on marine, human, and undersea life as well as agricultural productivity, this study suggests using such waste material as a chemical additive in concrete manufacturing. In order to ascertain the impact of UEO on the various fresh and hardened characteristics of concrete, an experimental program is originally presented. To determine their impact on the qualities of new concrete, such as workability as measured by the slump, compaction factor, and initial setting time, concrete mixes of the M20 grade will be created with varying amounts of UEO and Superplasticizer. The effectiveness of concrete usually contains UEO (0%,0.25%,0.50%,0.75%,1%) and Water Reducing Agent (WRA) as Superplasticizer (0%,0.50%,1%) will then be thoroughly studied through the evaluation of the various material properties, including the concrete’s compressive strength at 7 days and 28 days as well as its tensile strength and flexural strength.

Key words: Waste materials, Used-Engine oil, Environmental impacts, Superplasticizer, Admixtures.
