Este artículo investiga el uso de escoria de cobre (EC), residuo masivo de la industria minera, como material cementicio suplementario (MCS) en mezclas de hormigón con posibles usos en pavimentos, evaluando las propiedades mecánicas y durabilidad frente a agentes agresivos. Experimentalmente, se observó que reemplazar hasta un 20% (volumen) del cemento con EC no reduce significativamente la resistencia a la flexo-tracción (FT), y que un 10% de EC aumenta en un 3,3% la resistencia a la FT a largo plazo (360 días) respecto al hormigón de referencia (sin EC). Además, se registró una reducción de la profundidad de penetración de agua en un 36% y 38%, a los 28 y 90 días respectivamente. Se concluye que la EC tiene un uso potencial para mezclas de hormigón para pavimentos, con un adecuado desempeño estructural y un menor impacto medioambiental, aunque son necesarios estudios adicionales específicos de pavimentación para validar estos hallazgos.
