How does the use of lightweight aggregates affect concrete bench portability?

The use of lightweight aggregates in concrete benches significantly enhances their portability by reducing overall weight without compromising structural integrity. Traditional concrete is dense and heavy, making benches difficult to move. Lightweight aggregates, such as expanded clay, shale, or perlite, replace heavier materials like gravel, lowering the bench's weight by up to 30-50%. This makes them ideal for outdoor settings, public spaces, or temporary installations where mobility is key.

Additionally, lightweight concrete maintains durability and weather resistance, ensuring long-term usability. The reduced weight also simplifies transportation and installation, cutting costs and labor. For designers and builders, this innovation offers a practical solution for creating functional, movable furniture without sacrificing quality.

In summary, lightweight aggregates transform concrete benches into versatile, portable pieces, blending practicality with modern construction techniques.
