What component is added to cement to create concrete?

• A. Water
• B. Sand
• C. Aggregate
• D. All of the above

Answer: (D)

The correct answer is that all listed components—water, sand, and aggregate—are essential for creating concrete. Concrete is a composite material made by mixing cement with water, which initiates the chemical reaction necessary for curing and hardening. Water plays a crucial role in this process as it is the medium that allows the cement to hydrate, leading to the formation of the hardened structure. Sand contributes to the composition of concrete by providing bulk and strength while also aiding in achieving the desired texture. Lastly, aggregate—typically consisting of gravel or crushed stone—helps to provide the concrete with structural integrity and additional strength. The combination of all these materials—cement, water, sand, and aggregate—creates a robust and long-lasting building material known as concrete, making every component vital to the final product. This comprehensive mixture enables various applications in construction, highlighting the importance of each element in achieving the quality and functionality required for structural integrity.
