Meta developed artificial intelligence to manufacture carbon-reduced concrete, which was used for the flooring of a data center
In a groundbreaking move, tech giant Meta has employed a new concrete recipe in the construction of its latest bit barn (datacenter) in Rosemount, Minnesota. This innovative mix, which boasts a 35% reduction in carbon emissions compared to traditional concrete, is part of Meta's ambitious plans for several multi-gigawatt datacenter clusters.
The concrete formula, named ECOPact, is the result of a collaboration between Meta and construction company Amrize. It achieves this significant reduction by replacing about 40% of the cement component with industrial byproducts such as slag and fly ash. This substitution leads to an avoidance of approximately 0.5 tons of CO₂ emissions per cubic yard of concrete used.
The high-performance demands of the data center are met with a compressive strength of 4,000 psi. Meta's AI tools, BoTorch and Ax, have been instrumental in optimising the formulation using Bayesian optimization. This AI-driven approach has not only improved the concrete's performance but also cut the research and development time by half.
While Meta has not yet disclosed the total or absolute CO2 emissions footprint for the entire volume of concrete poured at Rosemount, the key metric of a 35% reduction relative to conventional mixes and 0.5 tons of CO2 saved per cubic yard offers a tangible estimate of its environmental impact.
Big Tech companies, including Meta, are actively seeking alternatives to reduce CO2 emissions from their datacenter fleets. The use of lower-carbon supplementary cementitious materials (SCMs) in the concrete recipe, as seen in the Rosemount project, is a significant step towards this goal.
It's worth noting that the performance of concrete can be affected by factors such as the types and proportions of cement, water-to-binder ratios, coarse and fine aggregate types, and admixtures. Time-consuming tests are needed to fully validate the performance of new concrete mixes, but Meta has published its code for developing low-carbon concrete under the MIT License, paving the way for further research and collaboration.
This innovation represents a significant step towards more sustainable construction for energy-intensive infrastructure like data centers. Meta's datacenter in Rosemount, Minnesota, initially draws 10 megawatts and is expected to increase to 75MW in the future, underscoring the company's commitment to sustainable growth.
