What is the name of concrete that has been enhanced by the inclusion of steel rods?

Reinforced concrete is the correct term for concrete that has been enhanced with the inclusion of steel rods, known as rebar. This type of concrete is specifically designed to withstand tensile stresses, which concrete alone cannot handle well, as it is strong in compression but weak in tension. The addition of steel rods allows the concrete to bear heavier loads and resist cracking or failure under stress. This combination takes advantage of the high compressive strength of concrete and the high tensile strength of steel, resulting in a material that is both strong and durable, making it ideal for various construction applications, such as buildings, bridges, and other structures.

Precast concrete refers to concrete elements that are cast in a controlled environment and transported to the construction site, rather than being poured in place. Pre-stressed concrete involves a method where the concrete is placed under compression before it experiences any service loads, which also enhances its durability and load-bearing capacity. Mixed concrete typically refers to the combination of concrete with various admixtures or aggregates to create a specific type or quality of concrete but does not necessarily imply any reinforcement with steel rods.
