Lightweight Aggregates Companies

The lightweight aggregates market size is projected to grow from USD 13.14 billion in 2025 and is projected to reach USD 15.52 billion by 2030, at a CAGR of 3.4%. In the construction industry, lightweight aggregates are used to make concrete and other building materials lighter. These aggregates consist of perlite, shale, expanded clay, and man-made aggregates like fly ash. As they improve fire resistance and lower structural load, they are utilized in concrete for bridges and high-rise structures applications. The use of lightweight aggregates is encouraged by government laws that support environmentally friendly building materials and the growing acceptance of green building certifications. This will propel the demand for lightweight aggregates market.
