Description
Nexclay 0-2 is a lightweight aggregate made from expanded clay in a rotary kiln at 1200°C. It is a natural product, lightweight, resistant, non-combustible, non-flammable and that remains unchanged over time.
Scope of Application
Mortars and lightweight plasters with good thermal performance and fire resistant. The mechanical and physical properties of the aggregate make it suitable for use in prefabricated elements with special features.
| Nexclay 0-2 | Declared value | Units |
|---|---|---|
| Particle size distribution | 0,25 - 5,6 | mm |
| Loose bulk density | 347 | (±15%) kg/m³ |
| Crushed and broken surfaces | P.N.D. | (% mass) |
| Crushing resistance (± 10%) | 5,1 | MPa |
| Water absorption | < 30,0 | (% dry mass) |
| Reaction to fire | Incombustible Euro Category A1 | - |
Recommendations for Applying
Nexclay can be used as a lightweight aggregate for mortars with studied batches. When making concrete or screed, make the mixture with only 2/3 of the intended water, then add the remainder at the end, to prevent the Nexclay to float due to excess water.
Supply
Nexclay 0-2 is available in packages with 1,5 m³ and 3,0 m³. It can also be supplied in bulk, loaded at the factory from the silo into a truck or tanker. The volume that is considered is the apparent, uncompressed volume, at the factory.
Shipping and Storage
During transport and/or storage the smaller particles might get segregated – Changes may occur in moisture content and the apparent volume might decrease due to rearrangement of the material, like with any other inserts such as sand and gravel.
Health and Safety
It is an inert product and does not constitute a hazard to health or the environment. In some applications, dust may occur and it is convenient to wear a protective mask.
