Effect of slag content and activator dosage on the resistance of fly ash geopolymer binders to sulfuric acid attack (2018, background): “However, geopolymer concrete produced with fly ash and slag has been shown to have between 50 and 90% less embodied CO2 than PC concrete [21]– [23].”
Use of Vietnamese rice husk ash for the production of sodium silicate as the activator for alkali-activated binders (2018, unknown): “Alkali-activated slag concrete has 73% lower greenhouse gas emissions (Davidovits, 1994), 43% less energy consumption and uses 25% less water than conventional Portland cement concrete (Jiang et al., 2014).”
Current Sustainable Trends of Using Waste Materials in Concrete—A Decade Review (2020, background): “[99] conducted an LCA of conventional, glass powder (GP), and alkali-activated slag concrete and compared the cradle-to-grate greenhouse gas (GHG) emissions, energy use, water consumption, and environmental toxicity for 1 m3 of 35 MPa concrete.”
