Abstract: This study examines behaviour of reinforced concrete subjected to corrosion. Concrete is the most extensively used building material in the world without a close alternative, due to this there have been major advancements in concrete technology and the need to reinforcing has been made indispensable. Traditionally the reinforcement has been carried out by steel, but the integrity of steel is greatly deteriorated by corrosion. This dictates the life of concrete in real condition. It has been observed that cement-based materials, on the addition of nanoparticles, develop distinctive properties at the molecular and nano level. In this paper, an experimental study on M30 grade conventional concrete columns and M30 grade concrete columns with 2% by weight of its cementitious materials replaced with nano-silica, subjected to varying degrees and different levels of corrosion are taken. The load is applied axially and the strength of the columns are compared. Concrete columns containing nano-silica shown an increase in strength by 20% compared to conventional concrete columns.
Keywords: Reinforcement, Corrosion, Nano-Silica.
