What is the basic composition of concrete?

Water and sand
Aggregates and paste
Cement and gravel
Air and water

The correct answer is: Aggregates and paste

The basic composition of concrete primarily consists of aggregates and paste. Aggregates typically include sand, gravel, or crushed stone, which provide strength and bulk to the concrete. The paste, composed of water and cement, binds the aggregates together, filling the spaces between them and facilitating the chemical reactions necessary for the concrete to harden and gain strength over time. The correct answer highlights the fundamental components of concrete as a composite material, which is crucial for understanding its properties and behavior in construction applications. A comprehensive grasp of these elements equips a batchman/operator with the knowledge to mix and work with concrete effectively, ensuring it meets the required specifications for various projects.
