What is concrete?

Concrete is everywhere, from our roads to our floors and our buildings. In an urban environment, it’s virtually impossible to go a day without seeing concrete. 

Concrete is made up of water, an aggregate, typically a rocky substance, and a binder, often a Portland cement or asphalt. Portland cement is the universal term used for the type of cement used to make nearly all types of concrete. Once combined, it is a tough substance. Once set and with proper mixing and pouring, it actually gets stronger over time. 

It’s used in building thanks to its incredible strength, flexibility, durability and cost-efficiency. Concrete is also naturally water and fire-resistant, so it is one of the most trusted building materials in the world. did you know six billion cubic metres is used of concrete each year? See why concrete the most used man-made material in the world?

How is concrete made? 

Concrete is a mix of typically portland cement, aggregate and water, at a mix of:

  • 10-15% Portland Cement 
  • 65-75% Aggregates 
  • 15-20% Water

Portland cement and water is mixed together to form a paste, then the aggregate (gravel, sand or stone) is added. Once the correct proportions are added, the concrete mixes as the agitator barrel rotate. Now it is ready to be transported to the construction site! As this formula is mixing the aggregates, they bind together, forming a strong substance. This strong substance is concrete! 

So what is in cement? 

Cement is the binding material used to make concrete. It is called Portland cement as a generic term, much like steel is referred to as stainless steel.

The ingredients for cement are extracted from generally extracted from various natural elements, like limestone, chalk, sand or clay.

Cement is made through combining:

  • Silica 
  • Alumina
  • Magnesia 
  • Iron Oxide
  • Calcium Sulfate 
  • Sulfur Trioxide 
  • Alkaline 
  • Lime
