Geopolymer

Forget Mixing, Just Add Water

Posted by: Joe Royer 5:00 minute read

The term “Geopolymer” was coined in the 1970s by a French scientist named Joseph Davidovits to describe a class of materials also known as alkali-activated cements. Typically, a sodium hydroxide solution is added to a cement to make an inorganic polymer chain — a long, covalently-bonded inorganic molecule with excellent strength and durability.

Geopolymers are also known to have some really good chemical resistant and physical properties, including fire resistance, and are highly sustainable as theyre made from recycled materials — a significant number of advantages over traditional solutions.

So, why aren’t others making geopolymers for commercial use?

Geopolymers are typically not industrially used because of

  1. the series of safety and environmental hazards associated with using a sodium hydroxide pH 12 solution on a jobsite;
  2. the fact that most contractors are not trained to handle those types of systems; and that
  3. most geopolymer systems require components to be added in a very specific proportion, in a very specific order. When mixed incorrectly, you end up with a poorly reacted product that doesn’t meet strength requirements.

When it decided to go into the geopolymer business, Milliken Infrastructure Solutions focused on solving those particular problems. We make a contractor-friendly geopolymer that does not require the use of an alkali activator. Rather than mixing multiple components together, we make a more commercially relevant system that is pre-blended and packaged in what looks like a regular cement bag. All the contractor needs to do is add water to the powder mix, and the product will act just like a cement. There is no need to worry about alkali-activated systems, a sodium hydroxide solution or the order in which you mix it—just add water and start working.

This cutting-edge materials science goes into every product in our broad selection of geopolymer-based products — all of which enable contracting and repair teams with the utmost in performance, durability and ease-of-use when conducting critical infrastructure repairs on surfaces, culverts, pipelines and more.

Stay tuned for next weeks installation when well delve deeper into what makes our geopolymer systems unique, and the myriad of applications that geopolymers can add value.
