The Difference Between Concrete and Cement
This video explains what is the difference between cement and concrete, a product used for masonry work around your house.
Concrete vs Cement Have you ever wondered what the difference is between cement and concrete? Well, wonder no more. In general terms, the word cement refers to any kind of binder that tightly holds other materials together. Concrete, on the other hand, is a mixture of materials like sand, gravel, and small rocks combined with any type of cement and water. The concoction is then allowed to dry
and harden. Basically, concrete is the stone-like structure formed after cement and other materials are mixed together. The cement is just a part of the recipe. Cement has been used as a binder of materiel for millenia. No one knows for sure who first came up with the idea to use a cement substance to bind materials together to make concrete, bricks, and other building materials. The process can be traced
back to Ancient Macedonia, but was more widely popularized during the Roman Empire. Early forms of cement used things like lime and pozzolana, a type of volcanic ash. The Romans were able to produce massive structures like the Pantheon and the Roman aqueducts using this formula. Currently, cement comes in two forms: Hydraulic and Non-Hydraulic. Hydraulic cement refers to any cement that uses water to begin a chemical reaction that hardens
the mixture and, when fully formed, creates a water resistant product. This reaction is independent of the water content of the mixture so allows for the material to harden even underwater. This makes it a very versatile construction material. Most all cements used today are hydraulic cements. Non-hydraulic cement uses materials that do not harden when...
