CONCRETE AND LIGHT SCREED BASED ON RECYCLED FOAM GLASS

Product catalog summary

Introduction
The Bernardelli Group introduces iLeggeri, a new line of lightweight concrete and screed products designed for the renovation market. These products are ideal for applications requiring reduced weight, such as the restoration of old floors and structural reinforcement in existing buildings.

Product Range
The iLeggeri range includes two main products: CLSLIGHT and CTLIGHT. Both products utilize recycled foam glass, offering ecological benefits and enhanced heat-insulating properties, making them suitable for LEED-certified buildings.

CLSLIGHT - Lightweight Structural Concrete
CLSLIGHT is a pre-dosed, ready-to-use lightweight concrete with a density of 1,800 kg/m³, providing a 20% weight reduction compared to ordinary concrete. It maintains a compressive strength class of 25/28 and is easy to use due to its S4 fluidity. It is ideal for structural reinforcement and restoration projects.

Compressive Strength: 28 N/mm² after 28 days
Exposure Class: XC1
Perfect for LEED buildings

CTLIGHT - Medium Drying Lightweight Screed
CTLIGHT is a lightweight screed with a density of 1,100 kg/m³, suitable for both indoor and outdoor applications. It can be walked on 10 hours after application and covered with tiles after 48 hours. For moisture-sensitive coatings, a waiting period of 8-10 days is recommended.

Compressive Strength: 7 N/mm² after 28 days
Flexural Strength: 2 N/mm² after 28 days
Thermal Conductivity: 0.30 W/mK
Reaction to Fire: Euroclass A1

Conclusion
The iLeggeri product line by Bernardelli Group offers innovative, lightweight construction materials that meet modern renovation needs while supporting sustainable building practices.

L Lightweight structural concrete RESISTANCE CLASS ✔ Perfect for LEED buildings ✔ Weighs 20% less compared to ordinary concrete ✔ Structural Lightweight structural pre-dosed ready to use concrete It is a light concrete that weighs 1.800 kg/m3: a weight saving of approximately 20% compared to ordinary concrete, while maintaining the same structural performance. It has, in fact, a class of compressive strength of 25/28. Its ﬂuidity - S4 - makes it easy to use even for complex castings. CLSLIGHT is used in situations which require low weight as a result of design requirements, such as in structural...
