New Polystyrene Beads for Lightweight Concrete and Light Screed - Thermal and Acoustic Insulation

New Polystyrene Balls for Lightweight Concrete and Light Coats

Our new polystyrene beads offer a solid option for preparing lightweight concretes or some light slabs. They surpass recycled versions thanks to their pure composition. expanded polystyrene (EPS) first choice. By replacing a portion of the usual aggregates, mixes are obtained with final densities that typically vary from 300 to 1200 kg/m³, depending on the quantities that are adjusted on site. To keep everything stable without the beads separating from the rest, it is wise to integrate our PSE ADDITIVE - which is also sold - because it promotes an equal and sustainable distribution in mass. These beads, produced here in France, are aimed at both entrepreneurs and private individuals who manage renovations, and they are delivered in bags or big bags at direct prices, without unnecessary intermediaries.

Features of New Polystyrene Beads

• Well-balanced lightness You didn't provide any text to translate. Could you please provide the text?

  With a specific density of 10 to 15kg/m³, they reduce the total weight of the preparations, which makes transport and installation much more manageable on a daily basis.

• Effective insulation You didn't provide any text to translate. Could you please provide the text?

  They boost the thermal and acoustic capabilities of the structures made, for example achieving a conductivity of 0.09 W/m°C for the lightest mixtures.

• Versatility You didn't provide any text to translate. Could you please provide the text?

  They integrate without any problem into various contexts, such as lightweight slabs or screeds for insulation. By combining with our PSE ADDITIVE, we avoid backflow problems and ensure reliable adhesion.

• Density You didn't provide any text to translate. Could you please provide the text?

  10-15 kg/m³.

• Diameter You didn't provide any text to translate. Could you please provide the text?

  Granulometry of 2-4 mm, which allows for smooth, seamless incorporation.

• Quality standards You didn't provide any text to translate. Could you please provide the text?

  Completely new, they achieve an M0 fire rating as soon as the cement dosage exceeds 350 kg/m³, and they hold up well against humidity without degrading.

Benefits of PSE Beads for Lightweight Concrete

1. Convenience at the meeting You didn't provide any text to translate. Could you please provide the text?

   Mixing is done effortlessly, uniformly, especially when thePSE ADDITIVE is part of the efforts to counter any dissociation.

2. Held over time You didn't provide any text to translate. Could you please provide the text?

   They limit water absorption to less than 8% according to the chosen formula, which strengthens resistance to external elements over time.

3. Optimization of efforts You didn't provide any text to translate. Could you please provide the text?

   Thanks to their thixotropic nature, they adapt to slopes without flowing, which speeds up implementation without added complications.

4. Mechanical robustness You didn't provide any text to translate. Could you please provide the text?

   We are talking about a compression between 0.8 and 12 MPa, with a good tolerance to punching up to 40 kg/cm² for common applications.

Applications of Polystyrene Balls Under Construction

• Creation of lightweight screeds for floors or slabs:

  Particularly useful in renovation where insulation counts double.

• Project plansinsulation against heat or noise You didn't provide any text to translate. Could you please provide the text?

  With sound reductions ranging from 25 to 40 dB on average.

• Custom Concrete You didn't provide any text to translate. Could you please provide the text?

  For roof terraces, half-timbering fillings, pipe cladding or even low-traffic lanes.

• Exterior facade insulation You didn't provide any text to translate. Could you please provide the text?

  Through projection, manufacturing of non-load bearing prefabricated parts, or mortars to assemble insulating blocks without weighing down the whole.

Tips for Optimal Implementation

Some advice from our technical documentation for flawless use:

• Example of dosage:

  For 1 m³ at 250 kg/m³ density, count 150 kg of CEM I 52.5 cement, 900 L of beads, 50 kg of sand, 80 L of water and 1.5 kg ofPSE ADDITIVE - it's a base that works well.

• For the preparation:

  First dampen the mixer, add the water followed by the cement and thePSE ADDITIVE, then gradually incorporate the beads and sand until you have a consistent dough, without any excess liquid that could ruin everything.

• To the application:

  Aim for a minimum thickness of 5 cm, cover with polythene for 4 or 5 days for drying, then leave for 2 days in the open air. It is better to work between 5 and 35 °C to avoid surprises.

• Regarding finishes:

  Wait 7 to 14 days before applying a P3 coating, which prepares the ground for tiles, parquet or carpet without risk of subsequent cracks.
