Reducing the effect of carbonation and corrosion in rice husk ash concrete by incorporating polymer

Abstract

Durability plays a vital role in life of a reinforced concrete structural member. To increase service life of a structure, it is important to reduce corrosion potential and carbonation attack. In order to reduce the corrosion and carbonation effect in concrete structures, various supplementary cementing materials are used. In this study, a novel composite is introduced to reduce corrosion potential and carbonation attack on Rice Husk Ash Polymer Modified Concrete (RHAPMC). An experimental work was conducted to check the behaviour of corrosion and carbonation attack in control concrete, cement was replaced with RHAPMC concrete at the ages of 30 and 180 days. The results indicate that the effect of corrosion potential and carbonation has been significantly reduced with the addition of polymer in the cement replaced concrete.
