ARGEX® 2-4

Description

ARGEX® 2-4 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

Lightweight concrete with good thermal and acoustic behaviour and structural lightweight concretes for special projects and for rehabilitation works. The mechanical and physical properties of the aggregate make it suitable for use in prefabricated elements with special features, such as blocks and arch bricks.

Recommendations for applying ARGEX®

ARGEX® 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 ARGEX® to float due to excess water.

Supply

ARGEX® 2-4 in 50-litre bags and 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.
