Concrete is a mixture of which ingredients?

Explanation:
Concrete is a composite material formed when a cementitious binder is combined with aggregates. The binder, cement, reacts with water to harden and hold everything together, while the aggregates—sand as a fine material and gravel as a coarse material—provide bulk, strength, and dimensional stability. Mixing all four components—cement, water, sand, and gravel—yields the durable concrete used in construction. The other options miss essential parts: cement and water alone form a paste, sand and water lack a binder, and lime and water refer to lime mortar, not cement-based concrete.
