Machine Learning Techniques in Concrete Mix Design

Concrete mix design is a complex and multistage process in which we try to find the best composition of ingredients to create good performing concrete. In contemporary literature, as well as in state-of-the-art corporate practice, there are some methods of concrete mix design, from which the most popular are methods derived from The Three Equation Method.

Jul 19, 2021  Many methods of normal concrete mix design produce the same proportion of cement and water content of concrete for different specific surface area of aggregate. Therefore, they often produce inappropriate workability of fresh concrete in the first batch.
