Invention
The findings of the present work provide a novel method for geopolymerization of the mixture of mine tailings and fly ash. This material can then be used in the making of construction products and materials. A protocol to make construction materials using the mixture of mine tailings and fly ash has been set up.
Applications
• Construction materials
• Bricks for Construction
• Road Pavement
• Pre-mixed concrete
Advantages
• The product made from the proposed invention has a very high compressive strength (40~65 MPa), which is comparable or even stronger than that of concrete.
• The curing time is much shorter than conventional concrete, about 3 days.
• The product can withstand water soaking. The product is more than 80% compressive even after a 30 day soaking.
