6a. Machine Learning & Prediction Disclaimer

CEMFORGE AND ALL ASSOCIATED TOOLS USE MACHINE LEARNING MODELS TO GENERATE PREDICTIONS ABOUT CONCRETE MIX PROPERTIES. THESE PREDICTIONS ARE STATISTICAL ESTIMATES BASED ON HISTORICAL DATA AND ARE NOT GUARANTEED TO BE ACCURATE, COMPLETE, OR SUITABLE FOR ANY PARTICULAR APPLICATION.

– You must independently verify all mix design predictions through laboratory testing and review by a licensed professional engineer before use in any real-world application.
– Sunnyday Technologies makes no representation that any predicted material property (including but not limited to compressive strength, tensile strength, workability, or durability) will match actual field performance.
– Use of any prediction, mix design, or technical output is entirely at your own risk. You are solely responsible for validating suitability for your specific application, materials, equipment, and local conditions.
