Aggrelite is made from the sintering process of fly ash . Aggrelite is formed into small round pellets, which are then processed to creates a very hard aggregates with a honeycombed internal spongy structure . These hard pellets can then be used as a superior, consistent, lightweight aggregate which is up to 50% lighter than natural aggregate. TYPICAL PHYSICAL CHARACTERISTICS OF Aggrelite: Aggregate Size mm : 2-4 , 4-8 , 8-16 Bulk Density : 750-900 kg/m3 Bulk Porosity : 35-40% Aggregate Strength : >4.0 MPa Water Absorption : < 16 % Shape : Round
1. Structural Lightweight Concrete:-Lighter in weight than standard concrete, but just as strong, AGGRELITE offers significant deadload savings. This allows for long cantilevers, slimmer general sections and reduced foundations sizes, enabling designers to produce structures that would be very difficult to build in other materials. 2. Floor and Roof Screeds:- AGGRELITE screeds are easily placed in depths from 30mm to over 450mm. They provide an excellent method of making up levels and offer thermal and sound insulation, which is especially useful on refurbishment projects. Only half the amount of cement is used than with a sand/cement screed, bringing time and cost savings. Density is also approximately half that of sand/cement screeds, again reducing costs. 3. Roof tiles:-Specially crushed and blended grades of AGGRELITE allow roof tile manufacturers to maximize strength and density, producing lighter units to reduce costs and dead load. 4. Land Drainage:- Allowing six times more water through its void space than gravel, AGGRELITE is an excellent material for drainage, either in slit trenching or in bulk. 5. Bulk fill:- AGGRELITE can be used bonded (with cement) or unbounded (loose) for maximum flexibility. It’s free draining properties allow significant reductions in hydrostatic pressure. AGGRELITE is low density and requires only limited compaction. 6. Precast:- AGGRELITE’s strong but light concrete offers 25% weight savings over normal concrete – ideal for cladding panels, floor decking, lintels, staircases and other structural units. 7. Horticulture – a growing medium:- AGGRELITE which can rapidly absorb up to 15% of its own weight when immersed in water. Water is then released over time to provide a controlled environment. 8. Filter Media:- AGGRELITE is an ideal material for use in biological filter systems where a bacterial film has to anchor and develop. 9. Refractory:- AGGRELITE has excellent thermal insulation properties and is a good fire resistant aggregate
