Fly ash and Silica fumes are the wastes from the coal and silica industries and poses serious problems of disposing. This present study focuses on the utilisation of Fly ash and silica fumes in the petroleum products soaked concrete. The effect of using fly ash and silica fumes on sorptivity, water absorption, strength properties, chemical characteristics-XRD, morphological behaviour(SEM) of petroleum products soaked concrete has been carried out. There has been a very comprehensive relation between concrete and petroleum. Concrete tanks are used to store petroleum in petrol bunks. Also petroleum comes in contact with concrete in areas like garages, automobiles servicing stations, storage tanks, etc. The bore hole used in oil extraction may be lined up with concrete. Petroleum poses high degree of adverse affects on concrete and thus degrades it. Petroleum gets penetrated into concrete and thereby flows into underground water. The spillage of petroleum on roads leads to cracking. The study aims at avoiding these effects by mixing concrete with different pozzolans like Fly-ash, Silica fumes. This technique is applied in the construction of roads, garage floorings and petroleum product’s storage tanks. In all of the above mentioned instances, petroleum comes in contact with concrete in one way or the other and has a specific impact on its characteristic behaviour. In this study, an attempt has been made to review the literature concerned with petroleum soaked concrete and also its advantages and drawbacks are highlighted. Keywords: Petroleum products, concrete, fly ash, silica fumes, sorptivity, water absorption, Compressive strength, Tensile stress, Flexural stress, XRD, SEM analysis. Introduction 1 Oil spills occur due to many reasons and this in turn has many fatal impacts on the environment. An oil spill on land may penetrate underground and move downward reaching eventually the groundwater. However, such vertical movement may be slowed down if prevented by the presence of paved surfaces, natural clay layers or other proper designed concrete. Oil may also move laterally along less permeable layers including surface pavements or with groundwater and surface waters. An oil spill in the underground such as from pipelines or underground storage tank leakage, will likely affect the groundwater since the vertical travelling distance is reduced. Such spill may also result in oil residuals that could be entrapped underground constituting a secondary source for groundwater pollution. Hydrocarbons are made exclusively from carbon and hydrogen atoms which bind *Corresponding author Nandini M.Naik is working as Associate Prof, Girish S.Kulkarni as Director and Principal ans K.B.Prakash as Principal together in various ways, resulting in paraffin’s, aromatics such as benzene, toluene, ethylene and xylene etc. Other individual compounds that are present in crude oil and oil discharges include sulphur, nitrogen and/or oxygen atoms too. Oil pipeline leakage and accidental oil spills are common problems in petroleum industry resulting into contamination of soil. Toxic heavy metals and petroleum hydrocarbons present in such contaminated soils can leach into the surrounding subsurface and groundwater, posing a threat to the environment and to human health. Petroleum- contaminated soil (PCS) is a mixture of sand, silt, clay and petroleum products (Meegoda and Muller, 1993). Concrete is one of the essential components used in building materials. Various admixtures are added to it to improve its quality (P. Van den Heede et al, 2012). Utilisation of fly ash and silica fumes in concrete improves mechanical properties and also influences resistance of concrete which is consequence not only of the chemical nature of the hydrated cement paste but also of its microstructure. The durability of concrete structure is determined based on the parameters like strength properties, serviceability over a specified period of time
