Portland Vs Geopolymer

Ordinary Portland cement is the second most used material in the world after water. It is also responsible for 8% of global carbon emissions (one ton of Portland releases one ton of CO2), trillions of gallons of freshwater usage, and millions of tons of waste rubble in landfills. Geopolymer cement is superior to Portland both in terms of performance and environmental impact. Geopolymers chemically fuse together while Portland-based cement creates cold joint and cracks from shrinkage. Across a wide variety of considerations, geopolymers simply come out on top.
