Abstract EN
This article presents the influence of granulated foam glass (GFG) on thermal insulation and mechanical properties of lightweight cement mortars.
The mortars were additionally modified with addition of ground perlite dust.
Ground expanded perlite waste was introduced into the cement matrix in the amounts of 10%, 20%, and 30% of cement mass.
The results show that application of this waste increases the strength of the mortars as well as decreases their thermal conductivity coefficient.
A series of mortars were prepared with introduction of granulated foam glass with mass per unit filler/cement ratio equal to 0.6, 0.9, and 1.2.
The aggregate composition of GFG was combined from different monofractions in the range 0–2 mm so that it filled the mortar volume to the maximum.
Additionally, mortars were made, in which 20% of 0–0.25 mm GFG volume was replaced with quartz sand with the same granulation.
Each mortar series was modified with addition of ground perlite waste in the amount of 20% of cement mass.
The results indicate an improvement of thermal insulation properties along with greater participation of perlite in the mortars.
The increase of the thermal conductivity coefficient was observed in the mortars, where the GFG was replaced with quartz sand.
Greater amount of GFG results in decrease of compressive strength, but it can be improved by replacing part of the lightweight filler with sand or by introducing the addition of ground expanded perlite to the matrix.
This also results in lower water absorption of mortars.
Research proved that in most cases, the addition of ground expanded perlite decreased the capillary sorption of mortars, as well as the water absorption coefficient by capillary action, with growing proportion of the lightweight filler.
