Ballast is dense material used as a weight to provide stability to a vehicle or structure. Ballast, other than cargo, may be placed in a vehicle, often a ship or the gondola of a balloon or airship, to provide stability.

At its core, ballast is added weight placed within a vessel to optimize its balance and buoyancy. This weight ensures that the ship’s center of gravity remains low enough to prevent capsizing while helping the hull cut through the water with greater efficiency.

Find out what a ballast is and why it's important in lighting. This guide explains the types of ballasts, their functions, and how they impact energy efficiency.

Ballast is a composite material typically made up of sharp sand and coarse gravel, used in construction projects to provide strength and stability. It is an essential component in creating concrete mixes, as it binds aggregate particles together when added to cement and water.

In general, ballast means something that provides stability or weight. In a specific sense, it’s most commonly used to refer to heavy material used to stabilize a vessel, such as a ship, especially when it’s not carrying cargo.

Ballast refers to material that is used to provide stability to a system, counteracting forces that may create instability. It serves as a foundational component, ensuring that structures do not sway or tip over under varying conditions.
