What type of material is reinforced concrete?

Answer 1

Concrete is composed of cement and other cementitious materials such as fly ash and slag cement, coarse aggregate made of crushed stone, fine aggregate such as sand, water, and chemical admixtures.

In reinforced concrete, steel is introduced in to the concrete.

In plain concrete, no steel reinforcement is introduced.

Generally tensile and compressive strength is taken by reinforced concrete and only compressive strength is taken by plain concrete

Answer 2

Yes, by definition reinforced concrete consists of 2 parts:

1. Concrete

2. Reinforcement

The reason for using reinforcement is that the concrete strength in resisting tensile stresses is weaker than it's strength in resisting compressive stresses, while reinforcement has much higher strength to resist both tension and compression stresses. So whenever your stresses exceed the concrete stress capacity, you use reinforcement to carrying these stresses.

Answer 3

When you add rebar which comes in many different sizes to the concrete pour like a footing or a slab for a basement or driveway it reinforces the concrete to less or if any cracking or breaking. Rebar is made of steel. You can also have fibers added to the concrete at a addition charge from the redi-mix supplier to reinforce the concrete which is less work and usually cost less then rebar.

Answer 4

Generally with steel reinforcing bars (sometimes fondly known as rebars).

Steel rebars are provided in tension zone of the beam x-section as concrete in very weak in tension.

Answer 5

currently, steel provides the best reinforcement material, but some applied sciences labs are working on making carbon based rebar that's 10 time lighter and 30 times stronger then steel

Answer 6

While concrete is great in compression, it's tensile properties are very poor. A reinforcement, typically steel, is used to improve a beam, slab, column etc in this area.
