Question: 1 / 400

What are the primary components of concrete?

Cement, water, aggregates

The primary components of concrete are cement, water, and aggregates. Cement acts as the binding agent that holds the other materials together, while water is essential for the hydration process that allows the cement to harden and gain strength. Aggregates, which include both fine aggregates (like sand) and coarse aggregates (such as gravel or crushed stone), provide the bulk and structural integrity to the concrete mix.

This combination of cement, water, and aggregates is crucial for achieving the desired properties of concrete, such as its workability, durability, and strength. The specific proportions of these components can be adjusted depending on the intended use of the concrete, but their presence is fundamental to any concrete formulation.
