Portable Concrete Mixer

Listing ID #3688773

Concrete is a very old construction material. Its early form appears in records from Ancient Egypt. It was the Romans, though, who used it the most. Many buildings and monuments in the Roman Empire were made of concrete. Their roads used concrete reinforced by other materials. At its simplest, concrete is a mixture of cement, water and aggregates like sand, natural gravel and crushed stone that you place in a concrete mixer for uniform mixing. It is the requirements of the project that determine the amounts used in the final concrete mix. If the mix is right, the final product is a material that has high compression strength.
