Introduction
For decades, concrete made from Portland cement has been the dominant building material across the world. However, Portland cement production is highly energy intensive and results in significant carbon dioxide emissions. With growing concerns over climate change, researchers have been exploring more sustainable and eco-friendly alternatives to Portland cement. One such promising alternative is geopolymer cement.

What is Geopolymer?
A geopolymer is an inorganic alumino-silicate polymer that can be produced from by-products such as fly ash, blast furnace slag and calcined clays. When activated by alkali solutions such as sodium hydroxide or potassium hydroxide, these materials form binding cements through polymerization process. Geopolymers have garnered immense interest as they utilize industrial wastes and reduce reliance on Portland cement, thereby lowering carbon footprint.

Production Process
The production of Geopolymer involves mixing an aluminosilicate powder source like fly ash with alkali activators like sodium hydroxide or potassium hydroxide solution. This results in a chemical reaction that transforms the aluminosilicate source into 3-dimensional geopolymer network. Compared to Portland cement production which requires heating limestone to 1500°C, geopolymer production requires much lower thermal energy input and therefore results in a greener concrete.

Properties and Performance
Several studies have shown that geopolymer concrete has comparable or even superior strength and durability properties compared to ordinary Portland cement concrete. It exhibits high early strength along with long-term strength, can withstand high temperatures up to 1000°C without significant loss of strength and has excellent resistance to acid, sulfate, sea water attacks. These properties make geopolymer concrete suitable for varied applications in construction industry.

Applications
Given its versatile properties and eco-friendly nature, geopolymer cement is increasingly being used across the world for infrastructure projects, residential and commercial structures. Some emerging applications are:

Road and Highway Construction: Geopolymers can be used to construct long-lasting roads, highways, bridges and pavements that are durable in diverse climatic conditions.

Precast Elements: Production of precast concrete elements like blocks, tiles, pipes etc using geopolymer allows for precise fabrication with less curing time.

Waste Immobilization: Geopolymers have shown potential for stabilizing toxic wastes and their immobilization reduces leachability and environmental liabilities of waste disposal.

Refractories and Furnace Linings: Ability to withstand high temperatures without degradation makes geopolymer ideal material for refractory applications in steel and copper industries.

Marine Structures: High acid and sulfate resistance of geopolymers allows their usage in marine environments for building jetties, sea walls etc.

Advantages over Conventional Concrete
The biggest benefits of using geopolymer concrete over ordinary Portland cement concrete are:

Lower Greenhouse Gas Emissions: Geopolymers do not rely on energy intensive Portland cement clinker production thus reducing nearly 80-90% greenhouse gas emissions.

Industrial Waste Reuse: Large scale use of geopolymers will significantly lower landfill requirement as fly ash and slag wastes get gainfully utilized.

Durability: Geopolymers last longer and require lower maintenance over life cycle compared to Portland cement based structures.

Fire Resistance: Ability to withstand high temperatures without damage makes geopolymers a suitable choice for fire prevention applications.

Acid Resistance: Resistance to chemical attacks like acid rain or industrial effluents reduces repair and replacement needs for geoopolymer structures.

Challenges and Future Outlook
Despite clear advantages, geopolymer concrete is yet to gain widespread acceptance and commercial adoption. High initial material and production costs coupled with limited standardization are major bottlenecks currently limiting its usage. However, as more research paves way for optimizing formulations to suit regional needs and mass production starts bringing down costs – geopolymer concrete is certain to become mainstream green building material of the future. Its unique properties and environmental friendliness establishes it as a strong sustainable alternative to Ordinary Portland Cement in years to come.

Concluding Remarks
In conclusion, geopolymer technology holds tremendous promise to transform the construction industry globally and aid climate change mitigation efforts. With development of standardized specifications and greater commercialization through large projects - geopolymers are poised for revolutionary growth. Their superior properties and eco-benefits over conventional concrete underscore the rationale for transitioning to this greener cementitious material at an accelerated pace.
