Behind every construction project lies a selection of aggregates and minerals that determines the strength, finish, and durability of the final result. This guide summarizes the most common materials and their main applications in construction.
Main Minerals Used in Construction
- Siliceous and limestone aggregates: the base of concrete and mortar, providing mechanical strength to the mix.
- Expanded clay: a lightweight aggregate used in lightweight concrete, green roofs, and insulation.
- Expanded perlite: a very low-density volcanic mineral, used as thermal insulation and in lightweight mortars.
- Pozzolana: a volcanic rock that, when finely ground, improves the long-term durability and strength of concrete.
- Gypsum and lime: traditional binders found in renders, plasters, and soil stabilization.
How to Choose the Right Material
The choice depends on the end use: structural concrete requires dense, well-graded aggregates, while thermal insulation or a green roof benefits from lightweight aggregates such as expanded clay or perlite. Grain size, mineral purity, and the origin of the material (own quarry versus intermediaries) also affect the result and the final cost of the project.
