For High strength concrete, the amount of cement is to be increased compared to normal strength concrete. The amount of cement in High varies from 420 to 650 kg per cubic meter based on the strength requirement. As the amount of cement is increased, the size of the fine aggregate is also to be increased compared to normal strength concrete.
