Concrete Aggregate
Concrete aggregate research focuses on optimizing the properties and efficient use of the granular materials that comprise a significant portion of concrete. Current research employs machine learning techniques, including artificial neural networks and deep learning models with multi-scale feature extraction, to predict aggregate properties (e.g., size distribution, resistance to fragmentation) from images or ultrasonic data, streamlining quality control and potentially reducing material waste. These advancements aim to improve concrete production efficiency, reduce reliance on laboratory testing, and enhance the overall performance and sustainability of concrete structures. The development of novel semi-supervised learning methods further enhances the efficiency of these predictive models.
