As Kriven explains, a motive for finding a replacement like geopolymer for traditional Portland cement is environmental: Portland cement production requires a tremendous amount of energy to heat and convert the raw materials (at 1450°C), and can generate nearly one ton of CO 2 for every ton of processed cement.
Some of this skepticism has been alleviated by the certification of our production plant and materials by agencies such as Underwriter Laboratories LLC, who have issued 5 designs to GPS for Spray Applied Fireproofing including certifications for our ASTM C119/UL263 and UL1709 mixtures, as well as CHPX7 (R39001). This design states that FP250 is ...

A process for producing a geopolymer includes combusting at least one of oil shale and mineral residues originating from a production of oil using the oil shale so as to produce a combustion product. The combustion product is ground. An alkaline activator is added to the combustion product to form a geopolymer mixture. Water is added to the geopolymer mixture.

Apr 04, 2017 · So application really matters when deciding to use geopolymer concrete mix designs. The material is also proving to be more economical than PCC. The jury is still out on which is a better material … for now. As an engineering material, geopolymer concrete needs more long-term studies and more time in use on its resume.
The color of geopolymer cement concrete is a function of the color of the fly ash, which can vary from dark gray to light pink, depending on the source. It is not unusual for fly ash from the same source to vary because its composition is affected by the combustion parameters at the power plant where it is produced.
The technology of geopolymer concrete is based on the idea of applying inorganic mineral substances, the production of which does not require the additional use of natural resources, and does not lead to CO 2 emissions into the atmosphere (byproducts of metallurgical, electrometallurgical industries and power plants).
