What is composition of plain cement concrete?

Plain cement concrete is primarily composed of three key materials: cement, aggregates, and water. The cement acts as a binding agent, while aggregates, which include fine aggregates (like sand) and coarse aggregates (like gravel or crushed stone), provide bulk and strength.
