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.

Automated summary

Through experimental analysis of mortars, it was found that the addition of fibers can improve the mechanical properties of the material and reduce shrinkage, which is beneficial for the use of recycled aggregates in mortar manufacturing. Carbon fiber has been shown to be the best performing reinforcing material in this statistical analysis.
