Nowadays the call for sand has accelerated immensely, inflicting deficit of appropriate river sand in diverse components of Telangana. Therefore, searching out an opportunity to river sand, Robo sand is determined economical. It competes absence of deleterious substances and higher fine makes it most effective to apply in concreting and plastering. Metakaolin may be a dehydroxylated form of kaolinite clay, that is taken into consideration to be a treasured mineral admixture having two times the reactivity of maximum of different pozzolans. Metakaolin reveals favorable engineering residences along with filler effect, acceleration of OPC, hydration and pozzolanic response which makes it beneficial to get replaced via way of means of cement. Steel reinforcement is high priced in creation enterprise to triumph over this difficulty, a fee powerful however secure constructional cloth is needed. Natural fibers may be one capability cloth, as they're in reasonably-priced and domestically to be had in lots of places. Taking most of these advantages into account, on this gift research the herbal coir fiber the use of metakaolin as cement substitute with completely changed Robo sand is used to triumph over the brittleness of the concrete.

This paper presents the use of modified method of constant voltage technique, electrical resistivity and corrosion potential measurements in determining the effectiveness of corrosion inhibitors' in concrete in arresting corrosion in the steel rebars in reinforced concrete specimens. Accelerated corrosion test is conducted on the different corrosion inhibitor mixed reinforced beams made with different cover thickness to understand the effect of cover thickness and type of inhibitor on the rate of corrosion based on the accelerated cracking initiated. Various inhibitors of corrosion, including calcium nitrite, sodium nitrite, hexamine and Diethanolamine, have been used in optimal dosage and investigated for their corrosion resistivity in concrete.
