Concrete Compression

Print Friendly

There are allot of new houses being built in Canada.

One possible material they could use is concrete. Concrete is a material that uses both reuse-able and non-reusable materials. It has sand, gravel portland cement,that are reuse-able. It also has a non-reuse able material, water. All of those materials make one of the most commonly used building materials Concrete is used not only on buildings but also on sidewalks. Concrete is is one of the stronger building materials with 5000-11000PSI ( Pounds per square inch), but it needs steel bars or rods to give it more strength in larger buildings. They’re 2 types of  ways  you can use the concrete and steel. It can be  used as reinforced concrete, which has bars in it or it can be prestressed concrete. It’s just like reinforced concrete but it uses rods. They stretch them but they put concrete on the ends then they let it dry and release the rods.

Concrete is inexpensive and easy to mix and pour. Concrete is stronger and better than wood, masonry, and plastic. Wood has 5000- 8000 PSI. Masonry has 1000-4000 PSI,  Plastic has 7000-12000 PSI. Concrete can have up to around 12000 PSI with steel.

Unfortunately, there are a few materials that can hold more strength against compression than concrete. Steel is the strongestmaterial on it’s own, with 25000 PSI. Next is aluminum with 20000-60000 PSI.

Concrete is inexpensive and very recouseful materail in buildings.
