| Summary: | Very little work has been reported on the influence of exposure topetroleum products on the chemical resistance of concrete. The work presented in this paper deals with the fundamental aspects of this problem. Therefore different chemical solutions are used to study the chemical effect on this type of tanks that used in petroleum storage.The effect of different additive fillers are used in prepared primer and are studied for different exposure media (moisture, 10% H2SO4, Oil) during 28 day residue time at 50 oc, and measure the penetration and chemical resistance of these samples. Two types of filler are used organic (charcoal 30 m particle size), and in organic (alumina 100 m particle size) to improve the chemical resistance of the prepared epoxy primer at different mixing ratio (st.s, Ch 1.2, 2.4, 3.6, A 1.2, 2.4, 3.6) respectively. A comparative analysis shows that high chemical resistance appeared for alumina samples than charcoal especially for optimum mixing ratio (2.4 Ep. / additives). Less effect of thickness on chemical properties appeared for standard sample and large effect of thickness for charcoal and alumina samples with preference foralumina especially at optimum thickness ( 2mm ) for alumina and ( 3 mm) for charcoal samples with 2% comparison effect of thickness.Also less effect of both moisture and oil compared to high effect of acidic solution (10% H2SO4 ) on the prepared samples with clear appearance to charcoal at 3 mm thickness and 1 mm for alumina. |
