AbstractField observation of efflorescence on masonry buildings resulted in a study of the contribution of bricks and a sandstone commonly used in construction in the area. Source salts in sufficient quantity to cause efflorescence were found in one of the bricks. Wick tests indicated that the remaining units provided a suitable media for passage of source salts from the mortar to the surface. Salts were identified. Quantitatively, the amounts of salts recovered from the wicks were compared with the absorption properties of the units and with their observed performance in the field. The possible effect of pore size distribution was considered.
