Evaluación de resistencia a la compresión de morteros implementando reemplazos de agregado fino por pollinaza generadas por empresas agropecuarias en el departamento del Atlántico, Colombia

The production of poultry waste (Pollinaza) has increased significantly in Colombia during the last ten years. Based on this, the use of this agricultural waste would result in a positive impact in favor of environmental sustainability, being represented through organizations such as the Colombian Council for Sustainable Construction (CCCS) at the national level, generating a positive economic impact through tax benefits for companies executing sustainable projects For this reason, the study examined the compressive strength of mortar cubes replacing, The study examined the compressive strength of the mortar cubes by replacing, in weight, the fine aggregate of the mix with Pollinaza, using manual crushing and ashing methods, applying replacement percentages of 10% and 15%, generating a total of 135 cubes, between control cubes and mix designs with pollinaza, which were tested at 7, 14 and 56 days in order to analyze their influence on the behavior and properties, both mechanical and physical, in the mortar mixes. The design of the mix and the characterization of the materials were carried out using the Colombian Technical Standard (NTC). Considering the expected strength of 17.5 MPa based on its classification as type M mortar, it was concluded that after 56 days of curing with 15% replacement of PC (Ashen Pollinaza), the highest compressive strength value was obtained, being 26.03 MPa, while the control sample reached a maximum strength of 19.66 MPa. On the other hand, the PT (Crushed Pollinaza) had a negative impact on the resistance, having its maximum peak of 3.05 MPa with 10% replacement at 56 days of curing; in this sense, it was evidenced that the resistance increases with respect to the increase of replacement of PC (Ashen Pollinaza). However, this mechanical property decreases in relation to an increase in the percentage of replacement of the crushed specimen, this due to the presence of organic material in the sample.
