AI for American-Produced Cement and Concrete
Meta is expanding its use of AI to help concrete producers create stronger, more sustainable, and more domestically sourced mixes. Its new open-source model, Bayesian Optimization for Concrete (BOxCrete), uses existing performance data and lab results to identify promising formulations faster than traditional trial-and-error methods. Early projects show that AI can improve curing speed and reduce cracking while supporting greater use of U.S.-made cement and materials. ## The Case for AI-Designed Concrete - The U.S. produces about 400 million cubic yards of concrete annually. - Although ready-mix concrete is generally produced domestically, roughly 20–25% of cement consumption is supplied by imports. - Concrete mix designers must balance: - Structural strength - Curing speed - Workability and slump - Cost - Sustainability - Traditional design depends on laboratory experimentation, engineer judgment, and historical knowledge, making it slow and expensive to adapt. - Different cements have different chemistries, so a formulation that works with one cement may fail with another. ## Supporting Domestic Cement Production - Greater use of U.S.-made cement could strengthen domestic manufacturing, jobs, and investment. - Reshoring and foreign direct investment have returned more than 1.1 million jobs to the U.S. since 2020. - The cement and concrete sector contributes over $130 billion annually and supports approximately 600,000 jobs. - AI can help producers reformulate mixes around locally available materials without compromising performance. ## BOxCrete and Open Data - Meta is releasing BOxCrete on GitHub as an open-source model for concrete mix design. - Compared with earlier models, BOxCrete is more robust to noisy data and can predict concrete slump, an important measure of workability. - Meta is also publishing the foundational dataset used to develop the concrete mix for its Rosemount, Minnesota, data center. - The associated research paper describes the model, data, and methodology. ## Results in Minnesota - Meta, Amrize, Mortenson, and the University of Illinois used BOxCrete to design a mix for a data center foundation. - The mix used domestically sourced materials. - It reached full structural strength 43% faster than the original formulation. - It reduced cracking risk by nearly 10%. - After meeting structural requirements, the mix was approved for use in additional parts of the data center. ## Industry Partnerships in Illinois and Pennsylvania - Meta is working with Amrize and the University of Illinois to apply AI to industrial-scale concrete production. - Amrize operates 18 cement plants, 141 cement terminals, and 269 ready-mix sites across North America. - Amrize has introduced a “Made in America” cement label and announced nearly $1 billion in planned 2026 investments, partly aimed at increasing domestic cement production. - Pennsylvania-based Quadrel integrated Meta’s open-source framework into its ready-mix software. - Quadrel uses the technology for data preprocessing, batch and test normalization, feature engineering, customer-specific model training, and quality-control workflows. - Its models improve continuously as new field-test results are incorporated. ## Adaptive Experimentation - Meta’s Adaptive Experimentation platform uses Bayesian optimization to search the large space of possible concrete formulations. - The system: - Learns from historical mix designs, laboratory results, and performance metrics. - Proposes candidate mixes likely to satisfy target specifications. - Compares the performance of domestic and imported materials. - Applies technical and ingredient constraints before testing. - Updates its predictions after each new experiment. Meta’s work suggests that open-source AI can make concrete development faster, more data-driven, and better suited to domestic materials. Producers can use BOxCrete and adaptive experimentation to reduce laboratory costs, improve performance, and support more sustainable and resilient U.S. cement and concrete supply chains.
