Concrete waste constitutes a type of construction and demolition debris (C&D). In the Peruvian context, there are regulations that properly manage the disposal and handling of these wastes. A solution is the production of mortars using structural concrete waste, which not only addresses the issue of environmental pollution but also reduces construction costs, promotes the circular economy, and encourages more sustainable construction practices. We seek to evaluate the percentage and fineness modulus (MF) of recycled fine aggregate from structural concrete on compression, adhesion, absorption, and density in mortar bedding. In the experimental phase, work was carried out with an Ico type cement with a cement: aggregate ratio of 1:4. Natural fine aggregate was replaced with rubble at 20, 40, 60, 80, 100%, of two types of fineness 2.5 and 2.8, maintaining constant mortar plasticity, and a comparison was made with the Rapimix mortar prepared by the Pacasmayo brand. In addition, none of the mortars were cured, to observe their real properties that are obtained on-site. The MF of the recycled aggregate 2.8 shows better behavior than the MF of 2.5. Therefore, the characteristics it presents are that compression and adhesion are growth parameters in a range from 0 to 40% of recycled aggregate replacing coarse sand, increasing the values from 101 Kg/cm² as a standard to 127 Kg/cm² and from 10.7 Kg/cm² of the standard mortar to 12 Kg/cm² respectively. In the case of density, we have values of 2575 Kg/m³ as a standard, and then this property decreases, and for absorption, it presents values of 10.6% as a standard and then gradually increases. Based on the results, it is concluded that a replacement percentage of up to 40% of recycled aggregate, combined with a fineness modulus of 2.8, offers optimal properties in bedding mortars. These results are consistent with the results obtained statistically through the analysis of variance method (ANOVA).
