“…The grain size variability is less marked in the sample collected from the plaster materials, except for Rev1 and ResC. The particle size distribution and clay content can have a significant influence on the plasticity of raw materials (de Oliveira Modesto & Bernardin, ; Dumbleton & West, ; Hajjaji et al., ). Sand, silt, and clay particularly exhibit a wide range of engineering characteristics (Mitchell, ).…”

Thirty rammed‐earth and coating materials collected from the Badii Palace wall in Marrakech were investigated for their particle size, chemical, and mineralogical characteristics. This was done in order to assess the original methods employed—and the provenance of the earth products used—during the Saadian period (XVIth century) construction of the palace. Differences in composition between the rammed‐earth and coating materials (and comparison with the local raw materials) suggest a different origin for these two materials. A high compositional similarity between the coating material and the corresponding rammed‐ earth is observed for the samples collected from well‐preserved walls. However, incompatibility between rammed earth and coatings was observed in many parts of the wall where the original coated materials have deteriorated by natural weathering and by the corrosive action of atmospheric pollution. The composition of coating material currently used for restoration shows the same incompatibility with the substrate and this is probably related to the same degradation problems. Finally, the influence of the semiarid climate in the degradation process is discussed. This study indicates constraints on the selection of the most suitable materials for sustainable restoration of these historic buildings.

“…There are various factors affecting the plasticity properties such as origin of geological formation, and mineral composition, particle size distribution, impurities (non clay minerals), and organic matter (Bergaya et al, 2006;de Oliveira Modesto and Bernardin, 2008;Hajjaji et al, 2010). The differences in the plasticity of the samples are almost understandable from the particle size distribution data (Table 1), i.e.…”

“…Following the development and mutations that the Tunisian economy has witnessed, there has been insatiable demand for the use of clays in the ceramic industry. Accordingly, in the last few decades many studies have been made on clays and their applications (Khemakhem et al, 2004;Baccour et al, 2008;Felhi et al, 2008;Mohmoudi et al, 2008;Baccour et al, 2009;Hajjaji et al, 2010;Moussi et al, 2011).…”
