The ceramic sector stands out because of the great potential to absorb various types of industrial waste, thus contributing to the preservation of the environment. There are two main reasons why countries recycle their industrial waste: i) the depletion of the stocks of raw materials; and ii) the increasing volume of solid waste [1]. The use of recycled materials in sectors such as ceramic industry represents a current concern with the issue of sustainability, but it can also reverse benefits in financial matters. The concern with fees and charges for the disposal of waste produced, as well as the possibility of saving the budget worksheet, causes interest in some investors to encourage researches that solve these problems. Researchers have studied the reduction of the consumption of clay, a non-renewable natural resource [2], and the incorporation of residue in ceramic tile composition [3, 4]. What remains to prove the effectiveness of the use of recycled aggregates is the certainty about the actual gains of the builders and the quality of the product manufactured [5]. The scheelite waste used in this research was collected from a mining complex located in the State of Rio Grande do Norte, Northeast of Brazil. The production of this mine corresponds to 20 tons per month, and for each ton, 250 kg of scheelite concentrate and 750 kg of waste are generated. There is an estimated 4.0 to 4.5 million tons of scheelite residue [6]. According to [6], these reserves grew 3.6% on average per year. In Brazil, the largest tungsten explorers from the scheelite are in the State of Rio Grande do Norte, in the Seridó region, which accounts for about 70% of the Mechanical properties of mortar produced with the replacement of natural sand by scheelite residue
