Nadu Mining presents its jumbo aggregate grade raw perlite, sized 1.2 – 2.8 mm (1200 – 2800 microns), the premier product at the top of our range designed to meet the most demanding specifications. This product is derived from the careful classification of the coarsest perlite ore and represents one of the largest particle sizes available. Its fundamental function is to produce expanded perlite aggregates that offer maximum volumetric efficiency, the lowest possible density, and the highest porosity.

This jumbo aggregate fraction has been specially developed for engineering and horticultural projects where structural lightness and void volume are of critical importance. Its primary applications include:

• Ultra-Lightweight Concrete and Screeds: Its expanded form is an indispensable aggregate for ultra-lightweight insulating concretes and fill screeds, particularly for green roof systems, inter-floor applications in older buildings, and on sensitive ground where minimizing load is essential.
• Drainage and Landscape Engineering: It creates a permanent drainage layer in the substrate of sports fields, golf courses, and large landscaped areas in regions with heavy rainfall, ensuring rapid water runoff and preventing root rot.
• Industrial Filtration and Bioreactors: The immense void structure created upon expansion is ideal as a carrier bed in biological treatment systems—offering a vast surface area for microorganisms—or for the pre-filtration of industrial liquids that require very high flow rates.
• Soilless Agriculture (Large Volume Systems): In growing media prepared for tree saplings or industrial plants cultivated in large pots and containers, it allows the root system to develop for years with ample aeration and without risk of compaction.

Our 1.2 – 2.8 mm jumbo aggregate grade raw perlite is the ultimate solution offered by Nadu Mining for projects aiming to minimize weight while maximizing performance.
