Análisis de propiedades del transporte de humedad en bloques de hormigón

Abstract

The moisture absorption properties in the concrete blocks have a significant influence on the performance of the penetration of rainwater. Knowledge of these properties is necessary to have technical information that allows the construction of walls with long life. In this paper we conducted a comparative analysis of two structural concrete blocks in relation to their physical properties and moisture transport: open porosity, specific mass and the initial rate of absorption (IRA), the total absorption and uptake versus time, obtaining the sorptivity as code for measuring the absorption accurate and reliable. The results obtained show that the sorptivity in the case of concrete block D2 is not applicable and presents the absorption average curve versus time as a characterization parameter with great potential, once can be observed the behavior of the blocks from the initial time to saturation, showing the characteristics between the different block types analyzed.
