A review of the influencing factors in the sclerometric assay

Abstract

The existing pathologies in reinforced concrete buildings occur due to several variables, one of the main ones is the lack of technological control during the construction, from which it is possible to predict or detect “non-conformities”. The lack or failure in this control can cause problems in structures, therefore, non-destructive tests (NDTs) emerged as methods to estimate the strength of the concrete and verify the need for repairs or reinforcements in the structures. The Sclerometric Test is an NDT that measures the surface hardness of concrete, providing elements for assessing the quality of concrete in new or old structures, helping to identify and prevent damage associated with durability and structural safety. This work aims to review the sclerometry test and its particularities, as well as to analyze the main factors that influence the test. Sougth to clarify questions about the advantages and limitations of sclerometry and to promote knowledge about the performance of the essay through a bibliographic review that presents debates between current norms related to the theme and published literature on some specific factors, these being: labor, types of cement and carbonation, besides presenting tests that help in the analysis of the sclerometric index.
