The primary building materials in cable-stayed bridges are steel, which is used in the cables and also as the reinforcing material in the concrete, which is the other primary building material.
In the context of TMT (Thermo-Mechanically Treated) bars, "Fe" stands for iron, which is the primary component of the bars. The grade designation, such as Fe415, Fe500, or Fe600, indicates the yield strength of the steel in megapascals (MPa). For example, Fe500 means the steel has a yield strength of 500 MPa. Higher grades indicate stronger steel, suitable for various construction applications.

MSBO steel, or Mild Steel, is a type of carbon steel with a low carbon content, typically ranging from 0.05% to 0.25%. This composition gives it good weldability, ductility, and malleability, making it suitable for various structural applications, including construction and manufacturing. MSBO steel is commonly used in the production of beams, plates, and other components due to its strength and versatility. It is often favored for projects where high tensile strength is not a primary requirement.
Gypsum can improve the workability and setting properties of concrete, but it does not significantly enhance the overall strength of the concrete itself. Instead, gypsum is primarily used to control the setting time of cement and to prevent flash setting. While it helps in achieving a more uniform mix and can contribute to durability, the primary strength gains in concrete come from the hydration of cement and the aggregate properties. Therefore, while gypsum plays a supportive role, it is not a primary strength-enhancing additive.
The primary ingredients of concrete—cement, water, aggregates, and admixtures—interact to create a durable construction material. Cement binds the ingredients together, water activates the cement, aggregates provide strength and volume, and admixtures enhance specific properties like workability or durability. The combination of these ingredients results in a mixture that hardens over time to form a strong, long-lasting material suitable for various construction applications.

Ni-Cu is a nickel-copper alloy, consisting of nickel and copper as the primary elements. It is commonly used in electronic components, marine applications, and in the production of coins. The addition of copper to nickel improves the alloy's strength and corrosion resistance.
The primary alloy used for lightweight aluminum applications such as aircraft and high-performance vehicles is 7075 aluminum alloy. It has excellent strength-to-weight ratio and good fatigue strength.
Architectural angle is for use were appearance is a primary concern over strength and is used in light duty applications. By appearance, architectural angle will have sharper more squared corners. Structural angle is designed with strength being primary to appearance. By appearance, it will have more rounded corners and a less "finished" look.
You need to say what you need primary material on - otherwise the question is unanswerable.
primary material for what? clothing, tools, etc.?
Keep Appointments is the answer. (C.)
Mercury is not considered strong in terms of structural strength or durability; it is a liquid metal at room temperature with low tensile strength. Its primary characteristics include high density and high surface tension, but it is not used for strength-related applications. Instead, mercury is primarily valued for its properties in thermometers, barometers, and other scientific instruments.

Steel was the primary construction material during the Second Industrial Revolution.
