Abstract
This paper studies the influence of oil products )gas oil and gasoline misname benzene) on strength and durability of high strength latex modified concrete. Three percentage (5, 7.5 and 10% by weight of cement) of styrene butadiene rubber latex (SBR) were used in this work to produce Latex Modified High Strength Concrete (LM-HSC). Epoxy protective were used as coating for all test specimens. Three exposure periods of oil products were used 30, 90 and 180 days after 28 days water curing. The experimental program in this research including; compressive strength, weight change, sorpitivity and initial surface absorption tests were performed. Generally the results showed that LM-HSC coated by epoxy has good resistance to the effect of oil products relative to LM-HSC without epoxy coating. The results showed that modification of HSC with latex SBR increased the compressive strength and lowered weight change, initial surface absorption, and longer period taken for the capillary soaking resulted in lesser sorptivity value, and in comparison with the HSC control concrete. All samples sunken in gas oil showed better results than samples sunken in gasoline this may be ascribed to the lesser viscosity of gas oil than gasoline.
