Abstract:
Mortars are composite materials that use natural resources in their constitution, such as natural river sand, as fine aggregate, and cement, as a binder. The use of natural aggregates has been causing a series of environmental damages throughout the world, which has encouraged research aimed at using new materials to replace natural aggregates. The objective of this research is to evaluate the potential for incorporating spodumene to replace sand, which is a natural aggregate. Mortars were manufactured in different replacement levels (0, 25, 50 and 1005), in which technological properties were evaluated in the fresh state, such as consistency, water retention and incorporated air content, and in the hardened state with mechanical resistance to compression and flexion, all in accordance with Brazilian technical standards. The results showed that replacing sand with spodumene, which is a waste material, presented satisfactory results, with little influence on the consistency of the mixtures, and improvement in some levels of mechanical properties. Thus, it can be concluded that there is evidence of potential application of this mineral residue in mortar applications, requiring further technological analysis
