Concrete Materials.ppt - SlideShare

Concrete = Filler + Binder Concrete is versatile construction material. The name concrete comes from the Latin word “Concretus” (meaning compact or condensed). Concrete solidifies and hardens after mixing with water and placement due to a stone process known as hydration. The water reacts with the cement, which bonds the other components together, eventually creating a stone-like material.
