### Concrete - Wikipedia

Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently a lime-based cement binder, such as Portland cement, but sometimes with other hydraulic cements, such as a calcium aluminate cement.

### Estimating the water-cement ratio of hardened concrete

At the water-cement ratio increases, the paste becomes more porous and more of the cement will have hydrated. (Strictly, the fineness of the cement should also be taken into account but that would mean another variable; with composite cements, the number of test mixes required would run into hundreds.
