Concrete mix design is a method of calculating right proportions of cement, sand, and aggregates for concrete to achieve target strength in structures. The Concrete mix design Concrete Mix = Cement:Sand:Aggregates. For a mix design of concrete, we have to follow various steps, calculations, and laboratory testing to find the right mix proportions.

Competence for the processes in the Cement Industry 6 The Cement Industry typically produces Portland cement – sometimes also masonry cement. Portland cement is a fine, typically gray powder comprised of calcium (from lime), silicates, aluminates (argillaceous), and ferrites, with addition of sulfates. Cement plants can operate continuously ...

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.

The contractor establishes the initial parameters for a mix design and serves as the starting point for subsequent proportioning calculations. The initial step in proportioning the mix design is to calculate the water content per cubic yard of concrete.

The raw mix is fed into a circular storage unit called a raw mix storage. Then, the mix is extracted transversely from the stockpile by reclaimers and conveyed to a raw mill bin called the raw mix bin for grinding. The other raw materials that are used in cement manufacturing, called additives, are high purity limestone, sand and iron ore.
