Pyrolite

Purolite is used as a component of lightweight concretes, heat and sound insulation compounds, as well as in agriculture and decorative design. Its unique microporous structure ensures low weight while maintaining strength and insulation characteristics, which is important for modern construction technologies.

Chemical structure and synthesis

Pyrolite is a predominantly amorphous material based on silica and aluminosilicates.

• Raw material: Natural rocks rich in Sio₂ and alo₃ are commonly used.

• The synthesis process: The raw materials are subjected to rapid heating (expansive heat treatment) to high temperatures, which leads to expansion and formation of a porous structure.

• Structure: The resulting granules have a rounded shape with many internal cavities.

Physico-chemical properties

• Density: Low specific gravity, which reduces the weight of the final structures.

• Thermal conductivity: Low thermal conductivity provides excellent thermal insulation properties.

• Porosity: High porosity and large surface area contribute to the adsorption of moisture and improve adhesion to the matrix of cement mixtures.

• Chemical inertia: It is stable in most aggressive environments.

Application

• Construction: It is used in light concrete, thermal insulation panels, plasters and plaster compositions.

• Decorative and finishing materials: It is used in decorative plasters and as a filler in plaster compositions.

• Agriculture: Improves soil drainage and aeration.

• Light fillers: It leads to a decrease in the total mass of structures while maintaining mechanical properties.

Conclusion

Purolite is a versatile lightweight filler that, due to its thermal insulation and structural characteristics, contributes to the creation of energy–efficient and durable building materials. Its use makes it possible to reduce the energy intensity of production and improve the operational qualities of finished products.
