E-Crete Geopolymer Concrete, Fly Ash Concrete

E-Crete TM. E-Crete™ is Zeobond’s proprietary geopolymer technology product. Consisting of fly ash, the by-product of burning coal at a power station, and slag, the by-product of steel manufacturing, E-Crete™ reduces the embedded CO2 of concrete by at least 60% compared to Ordinary Portland Cement (OPC) based concrete.

Geopolymer

What is a geopolymer? In the 1950s, Viktor Glukovsky, of Kiev, USSR, developed concrete materials originally known under the names "soil silicate concretes" and "soil cements", but since the introduction of the geopolymer concept by Joseph Davidovits, the terminology and definitions of 'geopolymer' have become more diverse and often conflicting.
