Durability Evaluation of Normal and High Performance Concrete

Classification of concrete is often most feasible means for measuring the durability and has become progressively over the past 20 years. The present study is focused on the capability of concrete to improve its durability when the concrete is subjected to the highly aggressive environments. Existing concrete in cold or coastal regions are affected by chloride penetration under the freeze-thaw cycles. This collective deterioration process quickens the damage advancement of concrete and reduces the service life of the structures. In real life the structure may face numerous deterioration contrivances due to environmental factors surrounded by the concrete. A variety of laboratory test method were used for the determination of durability, which provide number of results, such as rapid chloride penetration value, electrical conductivity, water absorption rate in concrete. For evaluating the durability of concrete, to a single contrivance of deterioration, the techniques were economical and appropriate. For determining the durability of concrete the Ordinary Portland Cement was used.
