This research attempted to study the "Effect of Used Engine Oil on Shear Capacity of Concrete Beam Containing Fly Ash." Due to the high cost for a proper waste disposal and the restrictions in environmental rules and regulations, it has become a trend nowadays to reuse processed and unprocessed industrial wastes as one of the materials in concrete technology. Leakage of used engine oil into cement concrete element in older cement grinding unit gives it a greater resistance to freezing and thawing. This property is quite similar to the admixture of concrete added with commercial air entraining agent. The chemical compound that found in the cement paste containing dosage of 0.15 % of UEO are quite similar to the cement paste contain 1 00% of cement. No hazardous or contaminated chemicals were present in the cement paste that could harm its properties. Ten full scale beams were fabricated to investigate the effect of UEO in concrete beam. Result shows that beam with 0.15 % UEO enhance its properties strength up to 32.26 % higher than that of normal concrete beam. This strength is quite similar to the beam added with commercial air entraining agent ( 4 5.3 9 %higher compared to normal concrete beam). Other cement replacement admixture, fly ash, rice husk ash, and super plasticizer were also been investigated with the used engine oil. The results were quite impressing and no significant effect in the ultimate load or load deflection behavior on concrete beam was observed.
