| Abstract: | English Summary A method to characterise the durability of the cement-stabilised compressed earth blocks which TC 164-EBM is committed to developing is described in a report [1] presented at the 49th Technical Session of the RILEM General Council. The objective is to develop a wetting-drying test on cylindrical cement-stabilised compressed earth samples to determine the decrease in their compressive strength. This artificial ageing test is defined by three parameters: the duration of immersion, the duration of drying and the number of cycles. For the experimental approach to these three parameters, this method anticipates a study of the evolution of the compressive strength of 2 series of cylindrical samples having different strengths after curing, according to the duration of immersion, the duration of drying and the number of cycles. This report presents results for the constants: drying temperature (70°C) and relative humidity (40%). Membres du TC: Président: A. Hakimi, Maroc;Secrétariat: M. El Kortbi, Maroc; N.
