There are many factors affected in durability of the bonded post tensioning system. Grout properties, concrete cracked, high permeability of grout and grout contain voids, bleed water etc. In bonded post tensioned constructions the grout acts as a last line of defense for preventing initial corrosion. Corrosion protection for bonded, internal, post tensioning tendonsare essential required in bonded post tensioning due to effectiveness of them. This report includes general study of durability aspects through grout with the practical site experience and know the status of grout and grout properties in post tension system. This report also include the study of grout procedure and grout material properties. Also gives the required properties for high performance of grout. Further, includes the final results after completion of exposure testing of grout material and updating the durability design guidelines to reduce the corrosion risk of the post tensioning system. Compressive strength of grout material, standard bleed test and flow cone test are performed in this project and cebex 100 chemical admixtures, and various water cement ratio are used to develop high-performance grout. The purpose of research is to develop a high performance grout for post tensioning tendon.
