In order to instigate the use of this new material as an alternative to promote greater sustainability and control in state works, this project aimed to study design aspects of ready mixed mortars with materials available in the region, including the addition of the ornamental stone waste (OSW), by-product generated in large volume and without specific disposal. For this, tests were carried out to verify the performance of the mortar with contents of binders replaced by this residue, in addition to tests to optimize the content of admixtures, to produce a mortar capable of maintaining its properties in the fresh state suitable right after mixing, that is, 0 h and after 24 h. Performance in the hardened state was also assessed, considering the same time of use of these mortars. Thus, to optimize the admixture contents mixtures were made with levels of 0.1,...
