Eternite Materials produces Aeternum™, a patented cement that can replace Ordinary Portland Cement in most applications while offering self‑healing, strength gain in water, and high resistance to salt, sulfates, and rebar corrosion. The cement is made from widely available aluminosilicate clays at a lower processing temperature, cutting energy use by about half and reducing CO₂ emissions up to 60%. It is available as a drop‑in replacement, a 50% OPC‑substituting blend (Aeternum‑S), or a 3D‑printable mortar for advanced construction projects.

Problem
Concrete structures frequently suffer from cracking, corrosion, and degradation, especially in harsh environments such as marine, oil‑gas, and high‑salinity settings. These failures lead to costly repairs, shortened service life, and significant carbon emissions from the production of traditional Ordinary Portland Cement (OPC).
Solution
Eternite Materials offers Aeternum™, a patented cement that replaces OPC in most applications while delivering self‑healing, strength‑gain in water, and superior resistance to salt, sulfates, and rebar corrosion. The product leverages widely available aluminosilicate clays and other common raw materials, enabling a lower‑temperature manufacturing process (≈750 °C) that consumes about half the energy of OPC and cuts CO₂ emissions by up to 60 %. Aeternum can be used directly as a drop‑in cement, blended as a secondary cementitious material (Aeternum‑S) to replace up to 50 % of OPC, or formulated as a 3D‑printable mortar (Aeternum‑3D) for advanced construction methods. The resulting concrete achieves a minimum compressive strength of 4,000 psi (30 MPa) in 28 days, improves to 8,000 psi (55 MPa) after six months in salt water, and maintains a brighter, more aesthetic appearance with lower heat absorption.
Target Audience
Primary customers are construction firms, infrastructure developers, and engineering contractors working on marine structures, oil‑gas facilities, high‑value pavements, and projects that employ 3D concrete printing.
Features
- Self‑healing chemistry that gains strength when exposed to fresh or salt water, reducing maintenance cycles
- Exceptional resistance to chloride, sulfate attack, and rebar corrosion, extending service life in aggressive environments
- Drop‑in replacement for OPC with compatible admixture usage, requiring no changes to existing mix designs
- Aeternum‑S formulation enables up to 50 % OPC substitution, improving sustainability while boosting strength and durability
- Aeternum‑3D mortar optimized for extrusion, powder‑bed, and impact 3D printing, supporting complex, nature‑inspired geometries
- Production at ≤750 °C uses roughly 50 % of the energy of OPC manufacturing, lowering cost and CO₂ emissions by up to 60 %
- Higher early compressive strength (≥4,000 psi) and continued strength gain up to 8,000 psi in saline conditions
