Lightweight Aggregate Mortars for Sustainable and Energy-Efficient Building

Abstract:

Self-leveling lightweight mortars were developed to attain good workability, sufficient compressive strength (at least 5 MPa after 28 days of wet curing), and low specific weight (less than 1100 kg/m³), as well as low thermal conductivity (lower than 0.3 W/m∙K). The attention was also focused on the sustainability of this construction material, which was improved by using in the mixture both glass reinforced plastic (GRP) industrial by-product as filler replacing limestone powder, and recycled aggregates replacing natural sand. GRP is a composite material made of glass fibres dispersed in a resin, usually polyester, widely used in several fields from building to furniture factory to boatyard. The recycled aggregates used were alternatively either wooden waste or polyurethane waste particles. Concerning wooden waste, they are produced by cutting, drilling and milling operations, where wood is removed from a finished product; they are sawdust and offcuts often collected in filter bags or dust collectors. On the other hand, the polyurethane waste particles were obtained as a rejection of a factory producing rubber soles for the footwear industry. The influence of GRP filler and waste particles on fresh mortar workability, compressive and flexural strength of hardened mortar, as well as on its thermal conductivity was examined. An optimization of the mortar mixture proportions was carried out by suitably varying the dosage of the ingredients. The experimental investigation showed that both the material unit weight and its thermal conductivity resulted strongly reduced, thus indicating a high and promising potential for future developments.
