Aggregates
Aggregates are inert granular ingredients, such as sand, gravel, or crushed stone, which, along with water and Portland cement, are an important component in concrete. Which is classified into two distinct categories, Fine and Coarse.
- Fine aggregates normally consist of natural sand or crushed stone with most participles passing through a 3/8inch sieve.
- Coarse aggregates are any particles larger than 0.19 inch, but usually range between 3/8 and 1.5 inches in diameter.
Aggregates must be pure, hard, and strong particles that are free of absorbed contaminants, clay coatings, and other fine materials that could cause concrete to deteriorate.
Tandis Parseh is one of the prominent trading companies promoting white clinker Type I-425 and Clinker Type II to local and international markets as it is the main ingredient in cement production. will deliver high-quality aggregate in a range of sizes to our valued clients, based on their needs.
