The Future of Low-Carbon Marine Concrete

Marine crete

Sustainable Marine Infrastructure

91% reduction in carbon emissions than Ordinary Portland Cement - higher durability, lower permeability, and superior resistance

The cement industry is the third-largest global producer of CO₂ emissions, with Portland cement alone accounting for 8% of the world’s CO₂ output. As industries push toward more sustainable solutions, ARC marine has developed a scientifically backed, proprietary low-carbon concrete designed specifically for marine applications.

This advanced Marine Crete technology delivers a 91% reduction in carbon emissions compared to Ordinary Portland Cement (OPC), while offering higher durability, lower permeability, and superior resistance to saltwater and chemical exposure.

Derived from low-carbon cement replacements known as AACM (Alkali Activated Cementitious Materials), this system utilises a pre-cursor such as PFA (Pulverised Fly Ash), GGBS (Ground Granulated Burnt Slag), or Kaolin, combined with a proprietary chemical activator. The exact formulation has been developed to the highest environmental standards and remains exclusive to ARC Marine
