The effect of salinization and salt crystallization on the techical parameters of lightweight repair mortars with expanded glass granules
Popis výsledku v původním jazyce
The novel lightweight repair mortar was designed and tested in respect to its resistance against salt crystallization and salinization. Natural hydraulic lime was used as the only binder, and the expanded glass granules were applied as lightweight aggregate. As reference, control mortar with silica sand aggregate was examined as well. The performed tests and analyses were aimed at the assessment of the structural, mechanical, hygric, and thermal properties of the 28-days and 90-days hardened mortars. Specific attention was paid to the evaluation of salt crystallization resistance and measurement of the effect of salt presence on the mortars’ hygroscopicity, which were tested for 90-days samples only. The use of expanded glass granules in composition of natural hydraulic lime-based mortar led to its overall functional and technical improvements, i.e. high porosity, low density, sufficient mechanical strength, improved water absorption and transport, enhanced thermal insulation performance, increased hygroscopicity, and resistance against salt crystallization. Taking into account the compatibility, functional, and technical criteria, novel natural hydraulic lime-based lightweight mortar was classified as repair mortar providing enhanced thermal insulation function.
