3 Factors That Affect the Design of Concrete Mix

From the Colosseum in Rome to the skyscrapers that fill the Manhattan skyline, the groundwork of all sturdyinfrastructures is a well-planned concrete mix. Designing a concrete mix involves a measurement and establishment process where the mix should be strong and durable enough for the designated structure.

The ingredients of a concrete mix can consist ofwater, fine and coarse aggregates, cement, reinforcement, soil, and other materials.Each ingredient has its own distinct properties. The minute differencesamong each of them make the task of forming the perfect concrete mix for a sturdy structure quite difficult. However, by using a Sakrete calculator and understanding the factors that greatly influencea concrete mix, you can create the right formulation. What factorsaffecta concrete mix design, then?

The Cement

Choosing the right type of cementdepends on what it will be used for. Sakrete currentlyhas 5types of cement for construction, each with its own distinct function:

  • Normal Portland Cement: Suitable for general concrete construction
  • Portland Pozzolana Cement: Widely used because of its high resistance to various chemicals
  • High Early Strength Cement: Commonly used in prefabricated construction and road work
  • Low-Heat Portland Cement:Used when heat intensity is kept to a minimum
  • Sulfate-Resistant Portland Cement: Used when the water or soil to be mixed in has a high level of alkali

When selecting a cement type for your structure, its performance should first be tested. This is to make sure that the chosen type will meet the requirements of your construction project.

The Aggregate Size

The size of the aggregate, both fine and coarse, is dependent upon the intended base and form of the structure. Coarse aggregates are pieces, usually of stone, that are bigger than 0.187 inches; the average size used in construction is around 0.374 to 1.476 inches in diameter. Fine aggregates, on the other hand, are usually sand or crushed stone that are less than 0.376 inches; the size commonly used in construction is around 0.787 inches in diameter.

The Water

The water used for construction work should generally have the same quality as that of consumable water. To ensure this quality, filter out any impurities like salt, organic matter, and other floating particles from the water. These impurities can adversely affect the concrete’s strength, durability, hardening, and setting.

The quality of a concrete mix’s design is a critical component for successful construction and a sound structure. Understanding the factors that influence the design of a concrete mix, along with using a Sakrete calculator, results in an accurate formulation for your building project.
