Study of the properties of lime and cement mortars made from recycled ceramic aggregate and reinforced with fibers

The construction and demolition waste can be used as an alternative with a lower environmental impact compared to the use of natural aggregates in the concrete and mortar manufacture. In this work, it has been performed an analysis of lime and cement mortar properties made with ceramic recycled aggregates reinforced with three types of fibers: glass, basalt and carbon. An experimental campaign has been carried out which includes the chemical and physical characterization of the materials and the statistical analysis of the results obtained. It has been proven that the addition of fibers improves the mechanical properties of the material and decreases its retraction, which favors the incorporation of recycled aggregates in the mortars manufacture. Based on the results obtained, it can be stated that carbon fiber is the best performing reinforcing material, as it has been demonstrated in this statistical analysis. •Recycled lime and cement mortars are a good alternative lining material.•The addition of fibers improves the mechanical properties of recycled mortars.•The addition of fibers improves volume stability caused by shrinkage.•Carbon fiber is the ideal reinforcing material for lime and cement mortars.
