Waste products like fly ash and ground-granulated blast furnace slag are used to create geopolymer cement . Thermal power plants produce fly ash as a waste product, and steel plants produce ground-granular blast furnace slag as a waste product.
Both fly ash and GGBS are treated using the proper technology and used for geopolymer concrete construction projects. By lowering the demand for Portland cement, the usage of this concrete minimises both the waste stock and carbon emissions.
The primary silicon and aluminium sources for geopolymers are thermally activated natural materials (like kaolinite) or industrial wastes (like fly ash or slab), which are then polymerized by an alkaline activating solution.
When compared to cement concrete, the drying shrinkage is significantly lower. This makes it ideal for structural elements made of thick, tightly confined concrete. Compared to cement concrete, it has a lower hydration heat.
In comparison to OPC-based concrete, the fire resistance is significantly improved.this concrete has a “low” to “extremely low” rating for chloride permeability.
Compared to conventional cement concrete, it offers reinforcing steel superior corrosion protection.When exposed to 2% and 10% sulfuric acids, this concrete was shown to have a very good acid resistance.
The Global geopolymer cement market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The most common type of man-made material is concrete. It is the second most used resource on earth after water. The main component of concrete, cement, has influenced much of our built world, but it also has a significant carbon footprint.
The solution is a zero percent Portland geopolymer cement developed by Geopolymer Technologies Ltd. using ash produced during the burning of fuel to generate energy. After being placed in a landfill, the ash is considered polluted soil.
By using this waste, geopolymers have developed the world’s longest-lasting acid- and heat-resistant concrete, which has a carbon footprint that can be reduced by up to 93%. Due to its longevity and durability, this is carbon negative and cost free over its entire lifetime.
