DURABILITY PROPERTIES OF NON-HYDROPHOBIZED LIME MORTARS WITH EXPANDED AGGREGATE: SALTS AND ICE CRYSTALLIZATION RESISTANCE
Original language description
Porous pozzolanically active aggregate can be used to prepare lightweight mortars with a high ability to salt accumulation from masonry and enhanced liquid water permeability. In this study, the comparison of non-hydrophobized expanded perlite, expanded glass, and expanded clay as lightweight aggregate in air lime mortars and natural hydraulic lime mortars has been investigated with emphasis on the resistance to salts and ice crystallization. The results of frost resistance tests were expressed as frost resistance coefficient for each mortar. The salt crystallization resistance of mortars were determined using 10% Na2SO4, 3% NaCl and 3% NH4NO3 solutions. The microstructure of mortars after the testing was monitored by scanning electron microscope and amount of anions absorbed in the mortars was determined by chemical analysis. The expanded aggregate significantly improved frost resistance of the mortars. The mortars with expanded perlite and expanded clay accumulated nitrates and sulfates to a greater
