Geopolymer Mortars and Resins for Extreme Heat, Chemical Attack and Low-Carbon Construction

Geoteria develops cement-free, inorganic geopolymer repair mortars and electrical insulating resins for furnaces, forges and other harsh industrial environments, where organic resins degrade and Portland cement cracks.

Why Conventional Resins and Cement Mortars Fall Short

Geoteria was created to overcome the limits of traditional repair materials in demanding environments.

Organic resins

At temperatures above roughly 300–400 °C, organic resins can degrade, release toxic vapors and odors, and may ignite.

Cement mortars

Even refractory cement mortars have limited resistance to thermal shock. A splash of molten steel on a concrete floor can cause serious damage.

Environmental footprint

Both resins and Portland cement carry a significant environmental cost. Switching to geopolymer chemistry is a practical first step toward a more sustainable operation.

After years of research with geopolymer scientists, Ecobeton has released a new class of geopolymer resins and mortars.

Four Performance Advantages of Geopolymer Materials

1,250 °C

Extreme fire resistance

Geopolymers tolerate severe thermal shock without burning or emitting fumes. Selected products withstand temperatures above 1,250 °C (2,280 °F).

Class R4

Rock-like strength

Mechanical performance comparable to high-grade Portland cement repair mortars (Class R4, EN 1504-3), with the durability of natural stone.

Acids & alkalis

High chemical resistance

Stable against chemicals that attack organic polymers. Resistance to sulfuric acid, hydrochloric acid and alkaline solutions is well above that of Portland cement.

Up to 80%

Lower CO2 emissions

Geopolymer concretes, cements and mortars can cut CO2 emissions by up to 80% versus Portland cement, and their longer service life spreads that footprint over many more years.

Performance values depend on formulation and application. See each product's technical datasheet.

What Is a Geopolymer?

Geopolymers are often described simply as a replacement for Portland cement. That view is only partly correct, and it can lead to design and application errors.

According to French scientist Joseph Davidovits, who coined the term, geopolymers are ceramic-like inorganic polymers produced at low temperatures. They are polymers in structure, so judging them by cement chemistry or ceramics alone is misleading. They are inorganic because their molecular chains are mineral-based, which is why geopolymer products do not burn.

This chemistry supports a broad family of materials, including mortars, resins, concretes, coatings, fiber-reinforced composites and specialty cements.
