Effects of used Engine Oil as Chemical Admixtures on the Properties of High Strength Concrete

High strength concrete was produced using locally available materials. Nowadays, there are many research conducted based on the processed and unprocessed industrial by-products and
domestic wastes as raw material in cement and concrete. This is a positive environmental impact due to the ever-increasing cost of waste disposal and sticker environmental regulation. The previous research shows that used engine oil have potential on increasing concrete strength and also acting as air-entraining chemical admixture to the concrete. The effect of using used engine oil in high strength concrete will be investigate and compare with concrete
with superplasticizer. This paper presents the results of en experimental investigation on the effect of different amount of used engine oil and water to binder ratio on residual compressive strength of high-strength concrete at 28 days. 10% silica fume used was used as cement replacement material for six trial mixes. Based on the results obtained the compressive strength at 28 days can reach 60MPa which is the target strength for this study. This study can be concluded that used engine oil can produce high-strength concrete up to 76MPa.
