Types of Stone – Concrete
Concrete may not come to mind as the most glorious of stones, but it is an extremely necessary one. Concrete is tough, dependable, and the foundation of many of our walkways and buildings. So, how is concrete made?
Mix it Up
Concrete is an artificial material. In fact, besides water, it is the most widely-used material. Rocks and gravel are mixed with water and rubber to create concrete. This ‘liquid stone’ is poured into place and allowed to set.
An Ancient Source
Romans had their own form of concrete. Silica oxide and lime were present in volcanic sand in the area. The Romans discovered that if it came into contact with water, it formed concrete. This used to be a major export for Rome.
Concrete can hold a lot of weight, but if it starts to bend, it will crack. Steel bars, plastic fibers, or glass can be added to concrete before it sets. This decreases the likelihood that concrete will bend.
Normally, when water hits concrete, it runs off. Pervious concrete, however, allows water to seep into the ground beneath it. This prevents urban flooding and stormwater pollution.
Nano concrete and microbial concrete are advanced forms of concrete. Nano concrete occurs from rapidly-spun, over-hydrated concrete and can be used for architectural detail or decorative molds. It is stretched out and lighter in appearance. Microbial concrete is a new area of research. Scientists are using this discovery to try and make self-healing concrete. The possibilities are endless!
