Development of ultra high strength concrete based on locally available materials and fly ash

Ultra High Strength Concrete (UHSC) is a concrete with a very high strength, high durability, large elastic modulus and very densed structure. It is widely used in construction of skyscrapers such as Petronas Twin Tower, Shawnessy Light Rail Transit (LRT) Station and Seonyu footbridge. The concrete...
