| Summary: | In the modern construction practices, industrial
wastes or by-products are largely used as raw materials in
cement and concrete. These impart many benefits to the
environment and bring-about an economic impact because the
cost of waste disposal is constantly increasing due to strict
environmental regulations. It was reported in literature that the
leakage of oil onto concrete element in older cement grinding
unit resulted in concrete with greater resistance to freezing and
thawing. This effect was thought to be similar to adding an airentraining
chemical admixture to concrete. This paper presents
an investigation on the load deflection behaviour and crack
patterns of reinforced concrete (r.c) beams subjected to four
point loading. Ten 120x260x1900 mm beams were cast with
100% ordinary Portland cement (OPC) concrete, 20% fly ash
(FA) and 20% rice husk ash (RHA) blended cement concrete.
0.15% dosage of admixtures (used engine oil, new engine oil,
and superplasticizer) was used throughout the experiment.
Results show that OPC and OPC/RHA reinforced concrete
beams containing used engine oil and superplasticizer exhibit
higher capacity, 18-26% than their corresponding control mix. |
