This research shows the obtaining and characterization of an Alkali Activated Binary Concrete (AABC). based on 70% of a natural volcanic pozzolan (NP) and 30% ground blast furnace slag (GBFS). as a real and environmentally sustainable alternative of replacement to the Portland cement (OPC)-based concrete. As the alkaline activator a mixture of sodium hydroxide and silicate was used. https://www.ofertastrailrunning.com/product-category/seasonal-art/
