Este artículo investiga el uso de suelo arenoso en la impresión 3D mediante su estabilización con cemento Portland y adiciones minerales (metacaolín y relleno de piedra caliza). El objetivo es hacer que el suelo sea compatible con el proceso de impresión 3D y garantizar la bombeabilidad. El programa experimental comenzó con una mezcla de referencia de suelo a cemento en una proporción de masa de 1:1 para lograr una consistencia adecuada para el método de extrusión. El estudio también examinó el contenido de aditivos químicos, la proporción de agua a material seco, la velocidad de impresión y las condiciones de altura de la boquilla.El análisis incluyó la reducción de cemento en dos mezclas, T15%C y T20%C, con proporciones de masa de 0.15:0.85:1 y 0.2:0.80:1. Se confirmó que se podían producir con éxito bloques de suelo-cemento con resistencias a la compresión de 3,1 MPa y 3,0 MPa para las composiciones T15%C y T20%C, respectivamente, indicando una reducción de cemento del 87% y 82% respecto a la mezcla de referencia (REFT100).
