High-performance SCC concrete with a mix designed to provide a low-permeability and high-durability was used in the walls and columns of Burj Khalifa tower. The C80 to C60 cube strength concrete used Portland cement, fly ash, and local aggregates. The C80 concrete had a specified Young™s Modulus of 43,800 N/mm2 at 90 days.
By changing the proportion of each of the constituent compounds in the cement (and other factors such as grain size), it is possible to make different types of cement to suit several construction needs and environment.
