Okay kiddo, have you ever played with building blocks before? Imagine those blocks are made of concrete, which is a hard material that is used to make buildings strong and sturdy. Rusticated concrete blocks are just like those regular concrete blocks, but they have a special design on the outside that makes them look fancy.
The design on the outside of rusticated concrete blocks is called rustication. It basically means that the edges of the blocks are made to look rough and uneven, kind of like the rocks that you see on a mountain. This design is created by using special tools to chisel away parts of the concrete surface.
Rusticated concrete blocks are used in building to create a special kind of texture on the walls. When they are stacked on top of each other, they form a pattern that looks like a bunch of raised and recessed rectangles. This pattern can be used to create an interesting effect on the outside of a building, and it can also add some extra texture and depth to the walls.
So, basically, rusticated concrete blocks are just like normal concrete blocks, but with a fancy design on the outside that makes them look special. They are used to create interesting textures and designs on the outside of buildings.
