Abstract

In order to improve the energy efficiency of buildings, there is a need to develop and utilize composites with good thermal, mechanical and durability properties in the construction of buildings. Comprehensive development and evaluation of energy-efficient fibre-reinforced composites for the construction of building walls are being undertaken at the University of Windsor. This paper presents some preliminary results on the influence of various recycled aggregates on the compressive strength, thermal conductivity, water sorption and ultrasonic pulse velocity (UPV) of the developed composites. In this study, a high volume of Portland cement was replaced with fly ash, and recycled concrete, recycled asphalt, recycled glass, and recycled rubber were used as a total replacement of the natural aggregates. The results of this study showed that the sustainability and thermal properties of fibre-reinforced composites can be improved with the utilization of recycled aggregates. However, there could be a slight detrimental impact on the compressive strength of the composites due to their lower stiffness/high water absorption. Nonetheless, fibre-reinforced composites with good mechanical and durability properties can be produced with recycled aggregates and used for the construction of walls in buildings in order to improve the energy efficiency of buildings.
