MICROCONCRETO DE ALTO DESEMPENHO: ANÁLISE DA TRABALHABILIDADE E RESISTÊNCIA A COMPRESSÃO

Abstract

The objective of this work is to carry out a systematic review of the literature on microconcrete, comprehensive of recent advances in the investigation of microconcrete, highlighting the main challenges and research opportunities in this constantly evolving area, in addition, to carry out tests focusing mainly on characterization methods and the effects of varying the water/cement ratio and the addition of superplasticizing additives on workability and compressive strength properties. The systematic review used the prism protocol to carry it out, while the methodology used for the tests includes the analysis of existing studies and carrying out laboratory tests to investigate the behavior of MCAD in different proportions of components. The results of the review showed possible research gaps such as microconcrete shrinkage can be controlled to improve the durability of repairs and that additives and aggregate replacements can increase workability and compressive strength. Tests demonstrate that the water/cement ratio has a significant influence on the material's properties, with lower ratios resulting in greater compressive strength.
