QC of cement using particle size and shape analysis

Perform particle size and shape analysis of cement particles to understand the flowability and water demand properties of the final product. The techniques of choice are either laser diffraction or dynamic image analysis depending on the data and requirements relating to the preferred tool for quality control.

Identification of phase composition in cement with X-ray diffraction

XRD is the go-to method for information about the microstructure and characteristic crystalline phases that originate from the clinker and cement manufacturing processes. Using Rietveld refinement allows the calculation of corresponding phase concentrations, and identification and quantification of both the crystalline and amorphous phases, at the desired data quality level.

Microwave digestion for cement industry samples

Microwave digestion facilitates ICP analysis of cement-related materials like limestone, clay, marl, secondary fuels, fly ashes and final products, ensuring effective digestion of complex samples. It supports compliance with environmental regulations and improves process quality.

Rheological investigation of cement

The MCR rheometer analyzes flow curves to compare additives and simulate stirring methods, ensuring cost-effective solutions and on-site workability. The Anton Paar Powder Flow Cell enables fast, reliable characterization of cement and fly ash, supporting precise material adjustments for construction needs.

Moisture content determination of cement

Moisture content directly affects the consistency, strength, and workability of cement. High levels of moisture indicate improper storage, which can cause caking or hardening. High cement quality can be ensured using automated drying ovens offered by the moisture analyzer Brabender MT-CA.

Characterization of the mechanical properties of cement

Optimizing cement's mechanical properties is crucial for durability and performance. Anton Paar indentation testers measure hardness across phases, comparing compositions reaching enhanced structural resilience. The nanoindentation system with a humidity chamber assesses the effects of relative humidity on hardness and elastic modulus, ensuring integrity under varying conditions. The indentation tester also monitors cement hardening, providing precise strength evolution data through repeated measurements.
