The First 3d Printed Geopolymer House!
We are happy to announce that in collaboration with RENCA and StrongPrint3D, Geopolymer International has printed the first ever 3D printed geopolymer house at our Nevada site. At almost 500 square feet, this house is a huge milestone for the development of both geopolymer and 3D printing technologies, and for our environment.

The First Industrial Geopolymer Mixer
Geopolymer International has now created the most successful prototype industrial mixer. We can now mix from 15 to 2500 lbs of binder to be able to create 6000 to 10,000 lbs of concrete every 20 to 30 minutes.

GeoPolymer International – Advanced Ceramic Cement Products

Geopolymer International’s signature line of advanced geopolymer (ceramic-cement) products includes GeoCement for casting and repair, GeoPrint for 3D concrete printing, and Geo Ceramic Spray for fire- and waterproofing applications.

These materials are classified under ASTM C1948/C1948M – Alkaline-Activated Materials for Construction (AAMC-RTC (HS)).

GeoCement is available in kits or in bulk as a three-component system, with the solid components supplied in bags and liquid components supplied in jugs or drums. One part of the GeoCement binder/cement can accommodate 1–3 parts filler or aggregate, depending on the specific application and performance requirements..

Detailed mixing and application instructions are available in both printed documentation and video format.

Sustainable Its inherent durability, combined with the materials' inherent eco-friendly characteristics, positions geopolymers as a prime choice for sustainable construction.
Fireproof This exceptional fireproof quality not only ensures the safety of occupants but also minimizes potential damage to the structure, thereby safeguarding investments and reducing the need for costly repairs or rebuilding after a fire incident.
Waterproof The unique chemical composition of geopolymers results in a dense, tightly packed molecular structure that significantly reduces porosity and permeability.
Acid Resistant Geopolymer building materials exhibit exceptional acid resistance, surpassing traditional alternatives like Portland cement-based concretes, which are vulnerable to acid attack and chemical degradation.
Low Cost Geopolymer materials can be sourced locally and from industrial by-products. Due to their high strength, less material is needed and cheaper aggregate or filler can be added. Their strength, greater durability, and fireproof properties also translate to lower repair and insurance costs.
Reusable Unlike conventional Portland cement-based concrete, which often ends up in landfills at the end of its lifecycle, geopolymers can be ground down and reused.

“Geo” refers to dirt/mineral and “Polymer” to long chains of molecules.

Geopolymers are human-engineered rock. They are the binder used before the invention of Portland cement. They are inorganic materials with a polymer molecular structure. Like natural rock, they are high strength and long-lasting, readily withstanding fire, freeze, flood, hurricane, and tornado. Most of the raw materials used for their production are of mineral origin. They can be crushed and reused over and over again.

By mixing our non-toxic mineral powders and a liquid silicate syrup, you have a nontoxic geopolymer glue that cleans up with water. Cast and print geopolymers to build new structures. Coat and spray them to fireproof, repair, and strengthen Portland or other surfaces. Use a variety of additives to adjust for strength, cost, color, texture, porosity, density, temperature, and curing time.

Ordinary Portland cement is the second most used material in the world after water. It is also responsible for 8% of global carbon emissions (one ton of Portland releases one ton of CO2), trillions of gallons of freshwater usage, and millions of tons of waste rubble in landfills. Geopolymer cement is superior to Portland both in terms of performance and environmental impact. Geopolymers chemically fuse together while Portland-based cement creates cold joint and cracks from shrinkage. Across a wide variety of considerations, geopolymers simply come out on top.

Why Ceramic Cement?

Geopolymers are the science behind our ceramic cement products.

Portland Cement

  • Uses over 1 trillion liters of fresh water a year
  • Responsible for 12-15% of the earth's pollution
  • 80-120 year lifespan
  • Requires water for mixing and cleanup
  • Not waterproof
  • Not fireproof
  • Not acid resistant
  • Low strength, high cost
  • Requires rock & sand aggregates
  • Cannot be used in freezing weather

Geopolymer Cement

  • Can be reused (no waste)
  • Geopolymer is 88%+ more sustainable
  • 10,000 year lifespan
  • Uses recycled or salt water for cleaning
  • Waterproof
  • Fireproof
  • Acid resistant
  • High strength, low cost
  • Utilizes a vast array of aggregates and waste
  • Can be utilized in freezing weather

Geopolymers and alkali-activated materials (AAMs) are often confused, but they differ in terms of chemistry and performance. At GPI, we produce aluminum silicate-based materials for a variety of applications. We are committed to advancing materials with enhanced functionality, resilience, and sustainability, while prioritizing safety and cost-effectiveness.
