In modern concrete, a variety of materials help make up aggregates, including sand and various sizes of gravel and crushed stone. Aggregates are divided into two categories based on particle size: fine aggregate, which is 0.2 inches (5 millimeters) or smaller, and coarse aggregate as large as 1.5 inches (38.1 millimeters).

Concrete - Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined.

How is concrete made? | HowStuffWorks

We've all seen concrete in action. Someone drives up in a truck, pours the gritty, wet concrete into the desired area and workers shape and smooth it into place. After it dries, you essentially have a custom-sized slab of rock -- only without having to cut blocks of stone out of the Earth. The technique is nothing new.

How Concrete is Made - Portland Cement Association

How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
