40-100Mesh
CENOLITE
2621900090
40-100 mesh low density cenosphere for construction cement materials. It reduces material weight, improves insulation value, and supports workability in cement mortar, panels, and lightweight construction products.
▸ This product is selected for construction materials that require lower density, improved insulation, and mineral durability.
▸ The hollow ceramic microspheres reduce material weight and help improve thermal performance in cementitious systems.
▸ Mesh size should be matched with mortar, slurry, panel, or dry-mix processing requirements.
▸ Weight Reduction: Low-density hollow spheres reduce the weight of mortar, panels, and cement products.
▸ Thermal Insulation: The hollow core helps lower heat transfer in building material systems.
▸ Cement Compatibility: Aluminosilicate chemistry is suitable for many cement and gypsum formulations.
▸ Workability Support: Spherical particles can improve mixing and application feel.
▸ Durable Mineral Filler: Inorganic ceramic particles provide stable long-term filling performance.

▸ Lightweight cement mortar
▸ Construction insulation panels
▸ Repair and leveling compounds
▸ Lightweight concrete products
▸ Cement-based insulation blends

▸Our in-house quality control laboratory is equipped with state-of-the-art testing instruments to ensure accurate and reliable measurement of all critical parameters:
• Laser Particle Size Analyzer (ISO 13320) – ensures precise particle size distribution for stable gradation in cement slurry systems.
• XRF Spectrometer – provides accurate elemental analysis (SiO₂, Al₂O₃, Fe₂O₃, CaO) to verify raw material and finished product consistency.
• Digital Density Analyzer – complies with ISO 787-10 for precise bulk density and true density measurement, meeting oilfield cement specifications.
• Moisture Analyzer – uses thermogravimetric analysis for accurate moisture content determination (≤0.3%), preventing negative impact on slurry performance.
• Hydraulic Pressure Tester (Compressive Strength Tester) – simulates downhole high-pressure conditions to verify the load-bearing capacity of cenospheres in set cement (30-50 MPa).
• Floatation Ratio Test Kit – ensures >95% floatation rate (98% typical) in standardized liquid media, preventing density segregation in cement slurry and guaranteeing uniform downhole performance.
