N2 - The objective of this article is to obtain geopolymer cement for the manufacture of shotcrete from the alkaline activation of mining tailings, which can improve the durability, resistance to compression, setting and fluidity of the shotcrete. For this, alkaline activators such as sodium hydroxide (NaOH) and sodium silicate (Na2 SiO3) will be used. Likewise, the standardized test will be carried out to determine the compressive strength of concrete in cylindrical samples, in order to analyze the mechanical properties acquired by the shotcrete made with geopolymer cement of 12 and 15M NaOH concentration. The results highlight the possibility of obtaining an eco-efficient cement with compressive strengths of up to 18 MPa at 28 days, reductions of up to 73% in CO2 emissions from the production of Portland cement and a sustainable alternative for the use of tailings.
