Evaluación de hormigones de alto desempeño en Guayaquil y su impacto en el análisis y diseño de edificaciones.

Abstract

This research focuses on the evaluation of the impact of High-Performance Concrete (HAD) in the structural design of buildings in Guayaquil, through the evaluation of mechanical properties and tests of beams for the analysis of tension capacity. The tests were carried out at the Holcim Innovation Center, following INEN and ASTM regulations. The results indicate superior mechanical properties of the HAD, highlighting optimized compressive strength, improved elastic modulus and optimized Poisson's ratio. In a 40-level project, outstanding efficiency is achieved in the use of materials, with notable reductions in the quantities of concrete and steel, generating significant savings in steel costs. The scope included laboratory tests and the comparative design of a building. The methodology included detailed characterization of concrete parameters and a comparative structural analysis. The efficiency of HAD reconfigures engineering paradigms, consolidating itself as an essential component in sustainable construction. As a key recommendation, the adaptation of dimensions and the implementation of long-term monitoring is proposed to further refine the use of the HAD in future projects.
