Abstract

Construction industry consumes around 40% of all extracted natural resources, produces large amount of waste from building demolition and it is highly energy consuming. Several approaches have been carried out to mitigate the environmental impact of construction practices, such as investigating on more sustainable binders and reusing demolition waste as recycled aggregates. Regarding the latter practice, an increased interest has been shown by the most recent European legislation, that strongly discourages extraction of aggregates from quarries or rivers, whereas promotes the reuse of large volumes of recycled materials. Aim of this experimental work is to produce cement mortars with high performance, uniform colour properties, minimizing or even eliminating efflorescence phenomena and environmentally friendly by replacing natural sand with recycled aggregates.
