Implementation of interaction diagram of the properties in fresh for mortars with ceramic aggregates

Abstract

As the natural resources needed for the construction sector are limited, new practices are being adopted for the management of waste generated nowadays, including the use of construction and demolition waste as aggregates for concrete and mortar. Considering the different typologies in construction wastes, ceramics are the second most representative material; therefore it is important to validate their feasibility as a total or partial replacement of natural aggregates. This work presents a study of the properties in fresh state (consistency, density and air content) of mortars containing aggregates obtained from recycled ceramics, and their influence on the subsequent properties in the hardened state. A statistical analysis of experimental data was carried out by establishing regression coefficients, and then a triple-entry graph was obtained, allowing the different properties of mortars to be easily linked and simplifying the prediction of the relationships they will present since the mixture design phase.
