ABSTRACT
The use of high strength concrete (HSC) in structures is increasing worldwide and has had a significant impact on construction in Malaysia. The most important breakthrough in the use of high strength concrete in Malaysia is the Petronas Twin Tower project. The project is part of a massive real estate development in Kuala Lumpur City Centre. The world's tallest building has been constructed with concrete columns, ring beams and a concrete core of 40 to 80 MPa (characteristic cube strength) with steel long span floor beams.
