Corrosion performance of rice husk ash blended concrete

Rice husk ash is one of the promising pozzolanic materials that can be blended with Portland cement for the production of durable concrete and at the same time it is a value added product. Addition of rice husk ash to Portland cement not only improves the early strength of concrete, but also forms a calcium silicate hydrate (CSH) gel around the cement particles which is highly dense and less porous. This may increase the strength of concrete against cracking. So far a systematic and detailed investigations on the corrosion performance of rice husk ash blended concrete is very scarce. Therefore, in the present investigation, a realistic approach has been made using different techniques such as compressive strength, bond strength, split tensile strength etc. Corrosion performance was evaluated using, open circuit potential measurements, rapid chloride ion permeation test and impressed voltage test and the results were discussed.
