English Abstract

Rdnforccd concrete structures are used from the turn of the century instead of steel plate for production.

Storage and transportation of oil because of the critical shortage of steel plate in some parts of the world f as well as because of, problems of serviceability, safety 7 and high maintenance costs associated with it.

The high permeability and deterioration of the concrete exposed to oil have made engineers always think to improve these properties of the concrete structure because it gives good indication about the durability and serviceability of these structures successfully.

Steel fiber concrete is one of the new fields of research in the concrete structures exposed to the oil products.

Different variables were used in this investigation i.e.

types of steel fiber (straight and end bent) with different aspect ratios s type of oil products (kerosene and gasoil}, and exposure periods.

The investigation studied three main parts and the effect of variables on the results.

The first part is concerned with the mechanical properties i.

e.

compressive strength, splitting tensile strength ? Flexural strength, and studies the stress-strain curve in compression.

The experimental results show that the ultimate strength of the concrete reinforced with steel fiber deteriorated less than the plain concrete when exposed to the oil products.

Also it is shown that the experimental stress corresponding to ultimate stress of the specimens also decreased significantly with stress reduction.

The second part studies the durability of steel fiber concrete specimens by studying the permeability and initial surface absorption of the concrete specimens.

The experimental results show that the presence of any type of steel fiber will decrease the permeability and surface absorption of all concrete specimens significantly.

The third part is concerned with the effect of oil products on the bond strength between steel fiber and concrete.

The experimental results show that the end bent fiber had higher bond strength than the straight fiber ; It is obvious from the results that the bond strength between fiber and concrete decreased significantly with increased oil absorption.

From the ail test results \ the performance of straight steel fiber concrete was better than that of the other steel fiber concretes used? It seems they deteriorate a little with oil products and have lower permeable matrix to oil products.
