Concrete mix design is a procedure of selecting the suitable ingredients of concrete and their relative proportions with an objective to prepare concrete of certain minimum strength, desired workability and durability as economically (value engineered) as possible.

The main topic is to start with the water/cement ratio that is the main responsible of the final concrete strenght and durability, but also the main responsible of cracking and heat generation.

The most expensive ingredient in concrete is the cement, so minimizing concrete costs means minimizing the amount of cement. Is there a practical minimum? Sure! Ideally, each piece of fine or coarse aggregate should be totally surrounded by cement paste and all the voids ... (gravel, sand, cement, admixtures, etc.), the two things that most ...
