Concrete mix design using the
double-coating method

Obtaining a concrete with certain properties fundamentally depends on the concrete mix design. The double-coating method will be explained in detail in this paper.

The behavior of concrete, whether fresh or hardened, generally depends on the behavior of its components and the relationship between them. Thus, obtaining a concrete with certain properties fundamentally depends on the concrete mix design. Concrete mix design usually includes two main steps: (1) selecting the main components suitable for the concrete (cement, aggregate, water, and additives); (2) determining more economical mix ratios to fulfill the workability, strength and efficiency requirements. Currently, there are many international methods locally approved for mix designs. They are all...
