| Summary: | [EN] Traditional concrete based on Portland cement has the advantage of being able to improve some mechanical properties with the addition of reinforcing elements such as metal fibers (SFRC) randomly distributed during mixing, with the help of additive technology of today, concretes can be very flowing or self compacting without sacrificing mechanical strength of the material, given a new generation of special concrete. The mechanical strength of the special concrete at an early age (early hours) and the retraction have not been studied in depth and so far have been treated separately. There are currently no standardized test methods accepted worldwide to measure these characteristics experimentally. In this paper will research in the scientific literature of the mechanical properties of concrete known to the present, in conjunction with an experimental program in order to measure the early hours: compressive stress, elastic modulus (Young's modulus), strength tensile bending (flexion traction), free shrink and shrink restricted (restricted ring test). It has experimented with 28 types of special concrete types (traditional, self-compacting synthetic fiber and metal) has been quantified and analyzed the results in this present work. ( |
