Abstract:
High-performance concrete (HPC) is considered to be a concrete in which its strength and durability are superior to that of traditional concrete. The HPC has characteristic compressive strength (fck) that starts from 40MPa and exceeds 100 MPa, the aforementioned characteristic is due to the addition of additives in its production and reduction of the water-cement factor, while the traditional concrete has a strength that varies from 25 MPa to 35 MPa. In the structural design, the fck of the concrete is considered, and through calculations it is mathematically observed that the higher the fck, the smaller the cross-sectional area of the steel used in pillars, beams, straps, among other elements, in addition, it is possible to observe that in a column that has a certain cross section, as well as beams and straps, if the characteristic compressive strength of the concrete is increased, the fck of the concrete that will be used, that is, the use of high performance concrete in the structure, the reinforcement ratio is maintained and the cross section of the column can be reduced, this situation reduces the weight of the structure, resulting in a lighter and less expensive structure.
