Concrete is used for a wide variety of construction projects, both big and small. It can be made in a variety of ways, but is most commonly composed of crushed stone, sand, cement, and water. There are two main types of concrete: Portland cement and ready mix. Portland cement is the most common type and is made from limestone, clay, and silica. It's mixed with water and then poured into forms to set. Ready mix concrete is created in a factory-like setting and contains all the necessary ingredients like gravel, sand, water, and Portland cement. It's then delivered to the job site via truck or rail car.
Concrete is used for a variety of things, but it is most commonly used as a construction material. A concrete mix is made up of three parts: aggregate, water, and cement. The aggregate can be anything from sand to gravel to crushed stone. The water helps to bind the ingredients together, and the cement provides the strength. There are different types of concrete mixes depending on what the final product will be used for. For example, a lightweight concrete mix would be used for something like a sidewalk while a heavier mix would be used for a foundation.
