What is concrete made of?
Concrete is generally made of two main parts: the cement and the aggregate . The cement, which functions as the main binder or “paste” of concrete, has a consistency, stability, and structural integrity that is dictated by the amount of water that is mixed into it. The basic science behind it is that the cement paste has a very specific chemical reaction with water which causes it to crystallize and harden. When it comes to the water-cement ratio, the lower the amount of water in relation to the cement, the harder the cement. On the other hand, enough water should be added so that the cement is plastic and viscous enough to flow smoothly.
