This article outlines a numerical study on the benefit of using high-performance and high-strength concrete (HPC/HSC) for fabrication of concrete elements. A comparison is made between the cost of existing beams with normal strength concrete and optimized beams made of HPC/HSC. Background is given concerning the most essential properties of HPC/HSC such as strength, creep, shrinkage, carbonation, and fire resistance. Results indicate that it is necessary to improve the structural configuration of the beams to fit with 16 mm strand to achieve an economical solution. The direct cost reduction after optimization of the section was 15 percent. Other advantages such as approximately 35 percent reduction of the required amount of carbon dioxide to produce cement for the same type of beam, lower cost of transport, and a decreased dead weight of the structure compared with the use of normal strength concrete motivates the use of HPC/HSC for these types of structures.
