Geopolymer concrete is an eco-friendly material and can substitute to Portland cement concrete. It reduces the high CO2 emission produced by use of Portland cement in construction.
Dear Arturo E Schultz .. thanks for answering .. and for the reference.
With my personal experience, I dont want to call Geopolymer Concrete as eco-friendly or economical at this stage. More of practical applications have to be done and it needs ages to understand the overall behaviour of Geopolymer Concrete over the Portland Cement Concrete.
In simple words, Geopolymer Concrete is one and only one alternative to the Portland Cement Concrete with numerous benefits like improved durability under aggressive environments, better strength at an early age.
Geopolymer Concrete needs any pozzolanic material rich in Calcium Oxide, Aluminium Oxide and Silicon dioxide, that has to be activated in an alkaline medium to form bond with other neighbouring particles in the Concrete matrix..
Dear Panditharadhya B J ... thanks for sharing your point of view... and I really appreciate your answer..
Geopolymer concrete is an innovative and eco-friendly construction material and an alternative to Portland cement concrete. Use of geopolymer reduces the demand of Portland cement which is responsible for high CO2 emission.
Geopolymer cement appears to be the product produced by alkali activation of fly ash or blast furnace slag. Some have called Roman Concrete a type of geopolymer cement.
The difficulties in making geopolymer cement are that it requires strong alkali base and high temperature curing. Both of these require energy and have an environmental footprint.
I also wouldn't assert that geopolymer cement is eco-friendly and green without digging into the numbers.
A new group of promising construction material is geopolymer. geopolymer has good mechanical performance, durability, and fire and acid resistance. It can be cured and hardened at room temperature with 80%–90% fewer CO2 emissions than Portland cement
