Abstract
RHA is considered a by-product of burn rice paddies and usually contribute to waste management problem. But RHA can be a product of value since there is large amount of RHA being produced in the Philippines and it has been a growing problem on how to manage its disposal, thus using it as partial replacement of cement can minimize the problem involving its waste management. It was known that RHA is a material which is sensitive to fineness changes. In this study, the effect of particle size of RHA on corrosion performance of steel bars in concrete was investigated using impressed voltage test technique. Control specimen with no partial replacement and two particle sizes of RHA (75and 150 microns) with 10% partial replacement with cement are considered. All specimens have water-cement ratio of 0.5 and cured for 28 days. Degree of corrosion intensity and corrosion current curves were observed. Corrosion current curves yielded a result that ordinates of curves are generally and significantly lower for 10% replacement RHA with 75 microns. The estimated degree of corrosion intensity was also lower for RHA with 75-micron particle size.
