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.
Concrete Basics. In its simplest form, concrete is a mixture of paste and aggregates (sand & rock). The paste, composed of cement and water, coats the surface of the fine (sand) and coarse aggregates (rocks) and binds them together into a rock-like mass known as concrete.
Don't add water to the concrete mix to keep the proper water-cement ratio but work harder to place the concrete and possibly have significant voids. The easy answer is never add water on the site to concrete, but that answer ignores the reality of the placement dilemma.
As you can see, cement makes up only about 15% of the concrete by weight (11% by volume), with the remainder aggregate and water. This is one reason why concrete is such a cost-effective material for large projects - for every pound of relatively expensive man-made material (cement), one can make 5 - 10 lbs of the actual product (concrete).
