Influência do aditivo superplastificantes MC- TechniFlow 560 na trabalhabilidade e na resistência à compresão do concreto

Abstract

This study aimed to evaluate the influence of incorporating a superplasticizer admixture on the properties of concrete by analyzing its behavior in both the fresh and hardened states, with a focus on workability and compressive strength. The research sought to assess the technical feasibility of using this admixture in the production of structural concrete, considering its ability to increase the fluidity of the mixture without the need to increase the water content, thereby contributing to the improvement of the material's performance. The methodology consisted of producing concrete mixtures with the same basic material composition, differing only in the presence or absence of the superplasticizer admixture. Initially, a reference mix was produced, followed by the preparation of concrete containing the admixture while keeping all other mix design parameters constant. Workability was evaluated through the slump test, whereas compressive strength was determined using molded specimens tested at different curing ages. All experimental procedures were carried out in accordance with the applicable technical standards, allowing a comparison between the reference concrete and the concrete containing the superplasticizer admixture to determine its influence on the properties of the material. The results enabled the evaluation of the admixture's effect on both the workability of the concrete mixture and its compressive strength, providing information that contributes to improving concrete quality control and promoting the more efficient use of this type of admixture in structural applications.
