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.
As the geopolymer cement market continues to grow, a number of major corporations are turning to strategic partnerships and acquisitions to expand their market presence. These collaborations have enabled companies to rapidly expand into new markets and capitalize on existing opportunities.
BASF completed the acquisition of the remaining 50% of the shares of XG Sciences, a leading provider of graphene materials. This move strengthens BASF’s portfolio of products, allowing it to become a leading supplier of raw materials for geopolymer cements.
The transaction also provides XG Sciences access to BASF’s extensive global network, allowing it to expand its business in the geopolymer cement market.
Saint-Gobain acquired the Canadian-based business of Calix, which specializes in the production of geopolymer cements. This move gives Saint-Gobain access to more advanced technologies for the production of geopolymer cements and expands their competitive advantage in the market.
Additionally, Calix’s customer base and technology will enable Saint-Gobain to increase its presence in the geopolymer cement market. LafargeHolcim announced its partnership with AirCarbon, a company that specializes in the production of carbon-negative materials.
Through this collaboration, LafargeHolcim will use AirCarbon’s patented technology to develop eco-friendly and carbon-neutral geopolymer cements. This partnership will allow LafargeHolcim to create more sustainable cement products, as well as reduce their carbon footprint.
Sika and Novacem entered into a joint venture to develop and commercialize geopolymer cements. This partnership will allow Sika and Novacem to leverage their expertise in the production of geopolymer cements to develop and market new products.
Additionally, this collaboration will expand the reach of both companies, allowing them to access new markets and increase their market presence.
These major partnerships and acquisitions demonstrate a growing demand for geopolymer cements. As the market continues to grow, more companies are likely to enter into strategic partnerships and acquisitions to gain a competitive edge. These collaborations will enable companies to expand their presence in the geopolymer cement market and capitalize on the existing opportunities.
An industry leader in the foundry sector, ASK Chemicals GmbH, produces the geopolymer-based binder system known as INOTEC. INOTEC is a cutting-edge solution to precision casting that offers many advantages over conventional binders and helps to improve casting quality, lessen environmental impact, and increase process effectiveness.
Precision casting, commonly referred to as investment casting or lost-wax casting, is a manufacturing technique used to create precise metal components with complex geometries. Making the desired portion into a wax pattern, covering it with a ceramic shell, and melting the wax to create a hollow ceramic mold are the steps involved. The final cast component is created by pouring molten metal into the mold, allowing it to solidify, and then removing the ceramic shell.
The ceramic shell is formed and maintained in this process thanks to the binder. Traditional precision casting binders are often made of organic substances like zircon, colloidal silica, or ethyl silicate. However, these binders have drawbacks in terms of their effect on the environment, issues with health and safety, and general process effectiveness.
INOTEC, on the other hand, makes use of a geopolymer-based binder system that has a number of benefits. Inorganic substances called geopolymers are made from aluminosilicate precursors and alkali activators. They are ideal for precision casting applications due of their superior qualities, including high strength, chemical resistance, and fire resistance.
The enhanced dimensional stability of INOTEC is one of its main advantages. The possibility of dimensional errors in the cast components is decreased thanks to the geopolymer binder’s improved control over the ceramic shell’s expansion and contraction during heating and cooling cycles. Higher accuracy and tighter tolerances are the outcome, which is essential for sectors like aerospace, automotive, and healthcare where component performance and reliability are crucial.
In comparison to organic binders, INOTECTalso offers greater refractoriness. It ensures that the ceramic shell keeps its structural integrity during the casting process and can tolerate high temperatures without suffering considerable degradation. As a result, metals with high melting points, such superalloys, which are frequently employed in high-performance applications, can be cast.
The geopolymer-based binder technique also aids in improving casting quality. Excellent flow characteristics make sure that the wax design is completely and uniformly coated. This results in an enhanced surface finish, fewer flaws, and lower rework or scrap rates. The INOTEC dimensional precision helps to reduce the need for additional machining operations, which speeds up production and lowers costs.
INOTEC has a low environmental effect and is sustainable, which are all important benefits. Due to the fact that they may be made utilizing waste or industrial by-products, geopolymers are renowned for having a low carbon footprint.
A safer working environment for foundry employees is further ensured by the geopolymer-based binder system’s lack of dangerous volatile organic compounds (VOCs) and lack of hazardous emissions during the casting process.
INOTEC provides enhanced process effectiveness as well. The production cycle is accelerated by its quick curing and drying properties, which also shorten the overall lead time needed for casting production. This enables foundries to boost throughput and stick to strict production deadlines. Because of the durability and high shelf life of the geopolymer binder, casting results are dependable and repeatable and working durations are extended.
