Determinação de indicadores para recuperação de lajes maciças: estudo de caso

Abstract

The damages in concrete structures can be generated by failures in the various stages involving since the conception of the design, the selection of the materials, the execution, as well as the maintenance of the structure. This study focusses on applied solutions in structural rehabilitation with a practical approach by means of a case study. The objective of the research is acomparative study regarding the impact on the development of the work,considering two distinct techniques of rehabilitation of solid reinforced concreteslabs which presented after execution compressive concrete strength smallerthan the design values. For the \analysis, the composition of the unitary costs ofmaterials and services, per square meter of rehabilitated slab was developed.The impact of the services of rehabilitation of theslabs on the physical scheduleof the work was also calculated and detailed. In conclusion, an analysisofcosts and impact on the physical schedule ofthe work, as well as the suggestion of the best technique to be applied are presented.
