Problem
The construction industry faces increasing pressure to reduce its carbon footprint, particularly from cement production, a major contributor to CO2 emissions. Traditional methods of reducing cement usage often compromise the mechanical performance and strength of concrete, limiting their practicality.
Solution
Concretene offers a graphene-enhanced liquid admixture that improves the microstructure of concrete, enabling a reduction in cement content while maintaining or improving performance. This nanotechnology-based solution lowers the embodied carbon of concrete mixes without requiring new equipment or training at batching plants. By optimizing the formulation for low-carbon mix designs, Concretene delivers compressive strength uplifts in both ready-mix and pre-cast concrete applications. The admixture is designed to be cost-neutral at scale and compliant with building codes, facilitating widespread adoption in the construction industry.
Target Audience
Concretene targets concrete suppliers, construction companies, and engineering firms seeking to reduce the carbon footprint of their projects while maintaining structural integrity and performance.
