Reinforced concrete

Reinforced concrete is like making a super strong sandwich!

Just like how a sandwich has two pieces of bread (the top and bottom), reinforced concrete has two parts too - the concrete and the steel. Think of the concrete as the bread and the steel as the filling.

Now, why do we use steel in concrete? Because while concrete is strong in compression (squeezing), it is weak in tension (pulling). Steel, on the other hand, is strong in both compression and tension. So by putting steel inside concrete, we make it super strong and able to handle both squeezing and pulling forces.

To make reinforced concrete, builders start by building a framework of steel bars (also known as rebar) in the shape and size of the structure they want. Then they pour the concrete all around the steel bars, making sure each bar is completely covered.

Once the concrete dries and hardens, the result is a super strong structure that can withstand a lot of force!

Reinforced concrete is used in many things like buildings, bridges, roads, and even swimming pools. It's strong, durable, and can last a long time. That's why it's so popular!
