The Performance of used engine oil on high strength concrete : A Structural Behaviour of Reinforced Concrete Elements Under Static Loading

There is a current trend all over the world to investigate the utilization of
processed and unprocessed industrial by-products and domestic wastes as raw materials
in cement and concrete. This has a positive environmental impact due to the ever
increasing cost of waste disposal and stricter environmental regulations. Historically,
reference books on concrete technology and cement chemistry indicate that the leakage
of oil into the cement in older grinding units resulted in concrete with greater resistance
to freezing and thawing. This effect is similar by adding an air-entraining chemical
admixture to the concrete. Such information is not backed by any research study
reported in the literature. The objective of the research reported in this paper was to
investigate the effects of used engine oil on High Strength Concrete (HSC). The main
variables included the type and dosage of an air-entraining agent (commercial type, used
engine oil, super plasticizer), microwave incinerated rice husk ash, silica fume and
water-cement ratio of the concrete.
