Item Análisis experimental del uso de agua potable y agua de acequia del sector el Galpón ubicado en Quisapincha perteneciente al cantón Ambato, provincia Tungurahua en la mezcla de hormigón para determinar la influencia en la resistencia a compresión(Universidad Técnica de Ambato-Facultad de Ingeniería Civil y Mecánica-Carrera de Ingeniería Civil, 2026-01-14) Estrella Riera Karol Antonella; Pérez Maldonado Ruth Lorena; Universidad Técnica de Ambato-Facultad de Ingeniería Civil y Mecánica-Carrera de Ingeniería CivilThis experimental study investigates how the use of irrigation water from the El Galpón sector, located in the Quisapinçha parish of the Ambato canton, can serve as an alternative to potable water for the production of conventional concrete. The study focused on how the type of water used affects compressive strength, considering two different mixes with design strengths of f’c = 240 kg/cm² and f’c = 210 kg/cm². For this purpose, cylindrical concrete specimens were prepared, cured, and tested at 7 and 28 days. This methodology complies with the Ecuadorian technical standard NTE INEN 1573, which regulates this type of test. Tests indicate that samples made with potable water exhibited superior mechanical performance, achieving average compressive strengths of 299.12 kg/cm² and 262.07 kg/cm² at 28 days for the 240 kg/cm² and 210 kg/cm² mixtures, respectively. These results significantly exceeded the design specifications. Conversely, mixtures using irrigation ditch water reached 170.63 kg/cm² and 205.27 kg/cm² after 28 days. This represents a decrease of approximately 23.75% and 7.25% compared to the mixtures made with potable water, demonstrating a significant reduction in final strength and non-compliance with minimum regulatory requirements. The results indicate that, while irrigation ditch water allows for a mixture with a suitable appearance and satisfactory initial setting, it does not guarantee the final strength required for structural components. This compromises the safety and durability of structures. Therefore, it is concluded that the use of irrigation wastewater for structural concrete is not recommended; it can only be used for non-structural purposes and under strict technical control. This analysis emphasizes the importance of examining the quality of water used in concrete production, as it confirms that this component has a direct impact on the material's mechanical properties and the structural reliability of buildings.
