CORROSION STUDY ON ECOFRIENDLY JUTE FIBER REINFORCED TERNARY BLENDED CONCRETEN.K. AMUDHAVALLI AND S. PRABAVATHY
The increasing potency of pollution in the environment not only harms the natural development but also hasten the deterioration and corrosion of materials used in the construction. Enormous quantity of waste produced from different sources hinder the resources, occupying huge amount of land area and polluting the environment by releasing harmful gases. Now a days Solid waste management becomes a serious environmental concern. Sustainable increase of the cement and concrete industry necessitates the utilization of agricultural and industrial waste materials. Such waste materials used in this investigation are Rice Husk Ash (RHA) and Silica Fume (SF) with ecofriendly, cheapest natural Jute fibers. The development of Jute fiber reinforced ternary blended concrete (JBC) with 15% of Rice Husk Ash (RHA) and 7.5% of Silica Fume as cement replacement and addition of Jutefiber (0.25%, 0.5%, 0.75% and 1%) shows a potential alternative for OPC. Therefore, this research aims to identify the durability performance of JBC in aggressive environment. Corrosion studies of JBC using impressed current techniques are considered in this investigation. The level of corrosion of rebar in the concrete specimens is examined. Based on the result obtained, it is concluded that the mix CJ3RS have better resistance to corrosion.
