Recycled mortars for building construction

A study carried out by researchers from the School of Building at Universidad Politecnica de Madrid has shown how mineral wool waste can be a suitable alternative to the reinforced fibers currently used in building materials. Besides, they improved mechanical and thermal properties of the added products, avoiding their storage in landfills. The result is a new cement mortar that reuses insulating materials and reduces the use of sand, what it helps implement the criteria of circular economy in the construction sector. Building construction generates a serious environmental problem so the resulting construction and demolition waste can be used to replace part of the raw building materials. In particular, mineral wool waste from the insulation of homes has increased in recent years due to the increment in thermal and acoustic requirements.
