Hygrothermal behaviour and relative humidity buffering of unfired and hydrated lime-stabilised clay composites in a Mediterranean climate

Abstract

Three different basic mixtures were prepared, by mechanical compaction, with different types of clays: quarry fine, kaolinite, and bentonite. Two groups of mixtures were studied, the first group without lime and the second with the addition of 5% hydrated lime. A comparison between the measured hygrothermal performances of the mixtures and their micro structural composition was performed. Micro structural morphology and chemical composition was characterized using SEM with EDS, mineralogy using XRD, and porosity using gravimetrics/He pycnometry and N2 physisorption with BET and BJH analysis. Hygrothermal functional properties were characterised as moisture-dependant thermal conductivity, moisture-dependent heat capacity, vapour sorption isotherms, and water vapour permeability.
