Properties of high performance self compacting concrete continuously exposed in oil products

الملخص EN

Self compacted concrete (SCC) is a new generation of concrete.

Its behavior after exposure to oil products is still unknown.

This investigation includes producing SCC and investigate its properties after different exposure periods (28,60,90,120,150 and 180 days) to water or different oil products (crude oil, gas oil , motor oil and fuel oil ).

The mechanical properties (compressive strength, splitting tensile strength, modulus of rupture and static modulus of elasticity) and dynamic properties (Ultrasonic pulse velocity and dynamic modulus of elasticity), length change, total absorption and density of SCC were studied.

The results show that compressive strength, splitting tensile strength, modulus of rupture and static modulus of elasticity, ultrasonic pulse velocity, dynamic modulus of elasticity and density for SCC specimens continuously exposed to water are increase as the exposure period increased.

Generally the results indicate a reduction in all these properties as the exposure period to oil products increased.-
