What materials must structural normal weight concrete contain?

Structural normal weight concrete must contain a combination of components that ensure its strength, durability, and overall performance. The correct answer highlights that it must include potable or non-potable water, cementitious materials, and aggregates.

Cementitious materials, which can include Portland cement or other types of cement, serve as the binding agent that holds the mix together. Water is essential for the hydration process, enabling the cementitious materials to set and gain strength. Aggregates, which include fine aggregate (such as sand) and coarse aggregate (such as gravel or crushed stone), contribute to the concrete’s bulk and improve its structural integrity.

Combining these materials in specific proportions addresses the fundamental requirements for creating a robust and reliable concrete mix that can withstand various loads and environmental conditions. Therefore, the inclusion of all these elements is crucial for achieving the specifications of structural normal weight concrete.
