A review on various aspects of high performance concrete

摘要

The requirement for high-performance concrete has increased day by day due to its better performance. Due to its strength,durability, and high modulus of elasticity, high-performance concrete has predominantly been employed in constructinglarge-scale civil engineering structures, e.g., tunnels, bridges, pavements, and high-rise buildings. The various characteristicsof HPC, like workability, strength, modulus of elasticity, durability in terms of permeability of fluids through concrete,sorptivity, and resistance to chemical attack, have been reviewed in this study. The properties above are generally assessedwhile constructing any concrete structure. It is well known that a million numbers of pores are available in concrete structures.The interconnected pores affect the durability of the concrete, which can be reduced by using the SCMs. The mostused SCMs, i.e., ground granulated blast furnace slag, fly ash, and silica fume, in HPC, are the by-product of waste materialsobtained from industries and are harmful to the environment. Stringent environmental norms help reduce the varying degreesof environmental impacts of throwing away such waste products. The present study highlights the utilization of mineral andchemical admixtures, as the admixtures are used to enhance the chemical, physical and mechanical properties of concrete.The present study suggests reusing these waste materials to improve the performance of concrete, which impacts society.
