Datacenter Slab Pilot with C-Crete’s Cement-Free Concrete

April 2025, Greater Atlanta Area, GA

April 2025, C-Crete successfully completed a pilot project for a data center slab in Greater Atlanta Area to showcase the strength and sustainability of its revolutionary cement-free concrete. A key highlight of the pilot was how seamlessly C-Crete integrated into conventional construction practices. The mix was placed, finished, and cured using standard ready-mix trucks and finishing equipment—proving that builders can adopt cement-free concrete without any new tools, training, or processes.

The project involved casting a structural slab designed to withstand the operational demands of a modern data center. By replacing Portland cement with C-Crete’s ultra-low carbon formulation, the project achieved a substantial reduction in embodied CO₂ emissions—without compromising durability or workability.

Independent third-party testing confirmed that the concrete exceeded expectations, achieving compressive strengths above 7,000 psi at 28 days. The mix also surpassed key durability benchmarks, including Resistance to Sulfate Attack (ASTM C1012), Chloride Permeability (ASTM C1218), and
Alkali-Silica Reactivity (ASTM C1567)

This milestone not only demonstrated C-Crete’s readiness for high-performance commercial applications, but also underscored its potential to accelerate the decarbonization of the rapidly growing data center industry. With data centers being some of the most resource-intensive facilities in construction, adopting C-Crete’s cement-free concrete paves the way for a greener digital future.
