Corrosion of reinforced steel in presence of mineral admixture with concrete in acid media
O.S. Shehata; Noura Saad tantawy;
Abstract
Rice Husk Ash (RHA) obtained from parboiling plants could be used to
dramatically enhance the workability, strength and impermeability of concrete
mixes. Research that has been carried out in this paper has proved
efficiency that obtained by utilizing Rice husk ash even in small amounts
(5%to 20%cement replacements), the properties of concrete can be significantly
givingmore inhibition for corrosion of reinforcement in 1Mof each
HCl,H2SO4,HNO3,CH3COOHacid as aggressivemedia. Themeasurements
carried out by three electrochemical techniques. The results showed that
more efficiency of concrete blended with RHA, and the inhibition increased
with increasing%of RHA than that without it toward corrosion prevention
of reinforcing steel.
