Concrete mainly consists of:

🏗️ Main Constituents of Concrete

Concrete is a composite material made up of cement (binder), fine and coarse aggregates (filler and skeleton), and water (for hydration and workability). In modern practice, admixtures (chemical or mineral) are also routinely added to modify properties such as workability, setting time, and durability. All the options listed are valid constituents of concrete.

Key takeaway

Concrete = cement + aggregates + water + admixtures. No single constituent alone makes concrete.
