Concrete Institute releases geopolymer recommendations

Recently, the Concrete Institute, together with the Geopolymer Alliance, have recently published a recommended practice document on the use of Geopolymer Concrete.

Geopolymers feature a different kind of chemistry to Ordinary Portland Cement (OPC) by activating amorphous alumino-silicate materials such as fly ash and slag, with alkali-based chemicals such as sodium hydroxide and sodium silicate.

The Concrete Institute says that Geopolymer Concrete is superior to OPC, particularly in the drastically reduced level of carbon dioxide emissions generated in its production.

The document, co-authored by Parsons Brinckerhoff Geotechnical technical executive Mark Drechsler, is available in both soft and hard copy through SAI Global:

A PDF copy of the publication is also available via the Institute?s Resource
