Effect of using Sand Contaminated with Petroleum Products on Mechanical Properties of Concrete

摘要

The success of concrete and reinforced concrete in the construction of structures exposed to oil products depends on their strength and the age of service, in addition to the cost of construction and maintenance. Has already been diagnosed damage to many of the concrete structures exposed to crude oil and its products, such as oil reservoirs, foundations of machinery and floors of industrial buildings oil stores. Although many studies have been conducted on the behavior of hardened concrete exposed to petroleum products, the interpretation of their behavior is still vague and unclear and needs many other studies. The aim of the research is to explain the effect of the contamination of fine aggregate on some of the properties of the resulting concrete. An experimental program was implemented for this purpose. Fine aggregates were contaminated separately by benzene, gas oil and used-engine oil. The percentage of contaminations were 1.5, 3, 6 and 9% by weight of sand. The results of the tests showed a decrease in the compressive strength, tensile strength, bending strength and absorption which depends on the type and percentage of the oil product in the mix.
