Development, Characteristics, and Advantages Of High Performance Concrete
Normal or Conventional concrete is a mixture of cement, sand, aggregates, and sometimes admixtures. The same types of materials are used to design High-Performance Concrete with the addition of some special materials such as ground granulated blast furnace slag, fly ash, super plasticizer, and silica fume. High-Performance Concrete is mixed, placed, and cured in a special way. The mechanical properties of High-Performance Concrete exceed that of normal concrete and it has a higher resistance to aggressive chemicals. High-Performance Concrete is more durable even in severe environments and on most occasions stronger than conventional concrete which is why it has been used in bridges, tunnels, and high-rise buildings. High-Performance Concrete has other characteristics such as high modulus of elasticity, resistance to high abrasion, toughness and impact resistance, and the list goes on. The aim of this paper is to discuss how High-Performance Concrete is developed, its characteristics, and advantages over conventional concretes.
