Soprema – PERLIBETON Light Weight Concrete Aggregate (Medium Coarse)

Description

Soprema – (PERLIBETON) – LWIC Light Weight Insulating Concrete aggregate (Medium Coarse)

LWIC Aggregate is a hard, very porous, expanded mineral, used as a lightweight aggregate, similar to hydrous phyllosilicate minerals but is white in color and is produced from a silica based volcanic glass.  When heated this volcanic glass expands to form a lightweight aggregate used in concrete, plaster, stucco, tilt-up panels, masonry, tiles & bricks, roof decks, pottery, and many other cement based projects where a lighter weight concrete is desired. LWIC Aggregate is inorganic, non-flammable, and pest resistant.

LWIC Aggregate excellent insulating characteristics and is extremely light weight, because of this LWIC Aggregate is also widely used as a loose-fill insulation in masonry construction.  In this application, free-flowing LWIC aggregate loose fill masonry insulation is poured into the cavities of concrete block where it completely fills all cores, and crevices. In addition to providing thermal insulation, this aggregate enhances fire ratings, reduces noise transmission and it is rot, vermin and termite resistant. LWIC aggregate is also ideal for insulating low temperature and cryogenic vessels.

When used as an aggregate in concrete, a lightweight, fire resistant, insulating concrete is produced that is ideal for roof decks and other applications. LWIC is not used for load-bearing concrete. Mixing LWIC with concrete is a matter of proper portion; you must mix the correct ratio of LWIC aggregate, cement and water. The more LWIC aggregate in the mix, the higher the R value, but the lower the structural integrity of the cured concrete.

LWIC aggregate can also be used as an aggregate in Portland cement and gypsum plasters for exterior applications and for the fire protection of beams and columns.

Other construction applications include under-floor insulation, chimney linings, paint texturing, gypsum boards, ceiling tiles and roof insulation boards.

LWIC aggregate is almost six times lighter than normal concrete, it is also now in demand for green building applications saving energy. All architects and structural Engineers have taken best advantage in exploring its properties for various applications such as roof insulation, interior Plastering, Penthouse insulation, corrugated sheet insulation, shrunk filling and to reduce dead load specially cantilever structure. It is well accepted worldwide as construction grade for Light weight Insulating aggregate, added with Amorphous Silica and fiber reinforcement Applicable for any non load bearing surface.

Lightweight:

When you mix bulk LWIC aggregate to fresh cement, the mix becomes much lighter. This makes it easier to handle and transport, reducing both labor and transportation costs. Lightweight cement is great for projects that need to reduce weight on buildings.

Better Insulation:

LWIC aggregate infused with portland cement is great for insulating buildings. The tiny air pockets in perlite help trap heat, keeping buildings warmer in winter and cooler in summer. This makes it perfect for walls, roofs, and floors, where energy efficiency is important.

Stronger and More Durable:

LWIC aggregate infused cement can resist changes in temperature and moisture, which makes it last longer. It doesn’t break as easily as regular cement, making it great for places with harsh weather.

Fire Resistance:

Cement mixed with LWIC aggregate is also fire-resistant. LWIC aggregate infused cement can handle high temperatures, which makes it ideal for projects that need extra fire protection.

Basic Mix Ratio for LWIC Concrete:

• 90 lbs Portland Cement (White or Gray)
• 30 Quarts of LWIC aggregate
• 50 lbs Sand-Granular (Optional)
• 5.25 gallons of Water (Use less water for a thicker mix)

Proper mixing will assure the maximum yield and uniformity.  Low shear, low RPM mixers (Similar to plaster mixers) are recommended for best results.

1. Add all materials “except” the LWIC to the mixer; then mix until this slurry is fairly uniform.  Two minutes with a mechanical mixer (cordless drill) will generally suffice.  Add additional water if needed but AVOID A SOUPY MIX.  Excess water reduces strength and durability of concrete and can cause cracking, dusting or scaling.
2. Add the LWIC aggregate; then mix again only long enough for a uniform mix, generally another two to three minutes.  Excess water and/or under mixing may reduce yield and workability.  Over mixing may degrade the LWIC aggregate and increase concrete density, reducing yield.
3. Optimum mixing cycle usually determined with one or two trial “test” batches.
4. (Fiber Optional) For added strength add one pound of cut strand fiber per cubic yard of concrete.
5. (Sand Optional) For extra strength, you can add a little sand to the mix. Keep in mind, this will make the mixture heavier and reduce some of its insulation benefits. Make sure to adjust based on what your project needs.

LWIC aggregate Dust Safety Concerns

Inhalation of LWIC aggregate dust can cause coughing, shortness of breath, and other respiratory issues. However, this is classified as a “nuisance dust” because it contains less than 1% quartz, making it relatively harmless to the lungs compared to other dusts.

LWIC aggregate dust can still cause temporary respiratory irritation, especially if inhaled in large quantities over extended periods. It’s essential to handle the material in a well-ventilated area (outdoors when possible) and avoid creating dust clouds to minimize exposure. Also, wetting or applying water to the material before use can greatly reduce any perlite dust exposure.

LWIC aggregate Safe Handling Practices

To minimize inhalation risks when handling this material, it’s recommended to wet the material before use, work in well-ventilated areas, and avoid creating dust. Wearing a dust mask (N95) when handling large quantities can also help prevent respiratory irritation. Individuals with pre-existing respiratory conditions or allergies should take extra precautions.
