What is CONCRETE?

We have been living, working, studying in concrete building especially in urban areas. But here is a question appearing in our mind, actually, WHAT IS CONCRETE?


First and foremost, we would like to share a video to give a brief introduction about concrete:

Brief introduction about concrete: 

Generally, concrete, as the main materials that made up a building, it has been playing an important role in building construction since the Roman Empire. For information, during the Roman Empire, Roman concrete (or opus caementicium) was made from quicklime, pozzolana and an aggregate of pumice. However by now, concrete is primarily composed of

- Aggregate (coarse gravel or crushed rocks along with a fine aggregate)

- Cement (Portland cement which serves as a binder for aggregate)

- Water(for the process of hydration)

What are the uses of CONCRETE?

Concrete is widely used for making architectural structures, foundations, brick or block walls, pavements, bridges or overpasses, motorways or roads, runways, parking structures, dams, pools or reservoirs, pipes, footings for gates, fences and poles and even boats.

We will tell more stories about concrete for the upcoming posts, please stay tune. :)
