Concrete has been a staple building material for thousands of years.
It was first used by the Ancient Greeks/Romans back in 800 – 300 BC and was used in the construction of large arches, vaults and domes. The type of concrete used at the time was made using Pozzolana, (a form of volcanic ash), mixed with pumice and quicklime.
Today concrete is an entirely different composition but is still widely used in many forms of construction due to it’s versatility, durability and the fact that it’s incredibly energy efficient.
You can see modern concrete buildings everywhere but how much do you really know about this multi-purpose material?
Interesting facts about concrete you may not know …
It is the most widely used material on Earth in terms of volume –
Due to being incredibly practical to work with and the fact it is made up of the most abundant mineral on the planet, (Limestone), concrete is used twice as much in construction than any other building material.
It is highly resistant to both fire and water –
Concrete is one of the most durable building materials on earth which is why it is so widely used. It is also incredibly resistant to water and fire which is why it is used in the construction of bridges and underwater structures.
The Average Concrete Slab Weighs 145 Pounds Per Cubic Foot –
The weight of concrete varies considerably depending on it’s air and moisture content, however the average slab weighs around 145 pounds per square foot.
Concrete is the best material for building roads –
Due to it’s high compressive strength and the fact it can be manipulated with little to no effort, concrete is one of the most popular materials used to build roads.
The largest unreinforced concrete dome in the world was built by the Romans –
The Pantheon in Rome is one of the best-preserved of all Ancient Roman buildings. It was originally built as a temple but now serves as a church.
