Cement

Precise cement composition analysis is key to maintaining product quality and process stability. Wavelength dispersive X-ray fluorescence (WDXRF) provides fast, accurate, and non-destructive elemental analysis of raw materials, raw meal, clinker, and finished cement.

By enabling consistent monitoring of oxide ratios throughout the production process, WDXRF supports process control, reduces variability, and ensures uniform performance from feedstock to final product.

WDXRF has been applied throughout the cement production process—from raw materials to finished cement—demonstrating how precise elemental control directly supports process stability, product uniformity, and compliance with industry standards.

Raw materials (limestone, clay, additives): Monitoring elemental composition ensures proper blending and reduces chemical variability before grinding.
Raw meal: Precise oxide ratio control (CaO, SiO₂, Al₂O₃, Fe₂O₃) enables stable kiln operation and consistent clinker formation.
Clinker: Elemental balance checks help maintain target mineral phases, ensuring strength and reactivity in the final product.
Finished cement: Routine WDXRF analysis verifies product conformity and performance. Results can be evaluated according to ASTM C114, which defines standard chemical analysis methods for hydraulic cement.

The application notes below present actual measurement data from representative stages of cement production, highlighting the versatility of WDXRF for both process control and quality assurance.
