Innovation in concrete without cement used

We all know that world is passing through tremendous change. We are improving our services and trying new things. We damaged our world enough that now we need proper solution not just by stop use of fossil ancestor's liquid and solid gold but to re-use the waste that had been created us from last two centuries. The best way is to start using waste material like flyash with 💯% replacement for cement. 

I know that is not going possible for like another just 100 years. Big business tycoons who are holding all the strings of money attached which includes government, security services, your routine life basic products, water and everything on this 3rd planet from the Sun which called the Earth. 

Geopolymer concrete is and will be next biggest turning point in construction industry.
