The study of Cements, Plasters, Composites, and Ceramics by thermal analysis.

Thermal analysis can be used for hydration and dehydration studies on cements and mortars. Evolved heats and setting times can be studied along with composition analysis of the materials. Thermal stability and evolved gas analysis can also be used to obtain compositional data

Cement Analysis by the Pressed Powder Method on Benchtop WDXRF Supermini200 According to ASTM C114

“Cement is one of the most important materials for construction. Many kinds of hydraulic cements, including Portland cement, with various physical properties are produced by changing the composition of clinker minerals; therefore, it is important to control the chemical composition of cement products and interim products. ASTM C114-11 covers chemical analysis of hydraulic cement. In this standard, procedures of wet chemical analysis are mainly described and X-ray fluorescence (XRF) spectrometry is mentioned as an example of “Rapid Test Methods”. In practice, XRF spectrometry has been used for chemical composition analysis of cement owing to its simple sample preparation and high precision. This application note demonstrates quantitative analysis for Portland cement by the pressed powder method according to ASTM C114-11 on Rigaku Supermini200, a benchtop sequential wavelength dispersive XRF spectrometer.

Cement Analysis by the Fusion Method on Benchtop WDXRF Supermini200 According to ASTM C114-11

Cement is one of the most important materials for construction. Many kinds of hydraulic cements, including Portland cement, with various physical properties are produced by changing the composition of clinker minerals; therefore, it is important to control the chemical composition of cement products and interim products. Since the fusion method can eliminate sample heterogeneity, such as grain size and mineralogical effects, it is possible to obtain high accuracy for cement samples and also to establish calibrations using a variety of materials. Therefore, X-ray fluorescence (XRF) spectrometry by the fusion method has been the method of choice in cement production processes. ASTM C114-11 covers chemical analysis of hydraulic cements. In this standard, procedures of wet chemical analysis are mainly described and XRF spectrometry is mentioned as example of “Rapid Test Methods”.

Cement Raw Meal Analysis by the Pressed Powder Method on Benchtop WDXRF

“Cement is one of the most important materials in the construction industry. Since its physical properties and those of the concrete ultimately made from it depend on its composition, it is important to monitor the composition of the raw meal used to make the clinker.

Thanks to simple sample preparation and routine operation, short measurement times and high precision, X-ray fluorescence (XRF) spectrometry has become the technique of choice for elemental analysis at all points in cement production: from alternative fuels, raw materials and raw meal to clinker and final certification. Wavelength-dispersive (WD) XRF is the most commonly utilized analytical technique in the cement industry because it offers the highest throughput, precision and sensitivity, especially for essential light elements, such as Na, S and K.

Traditionally, WDXRF spectrometers used in cement plants have been large, floor-standing models with substantial installation requirements and ownership expenses. As the industry strives for greater efficiency, operators have increasingly sought equipment that is less expensive to acquire and less costly to maintain. This application note demonstrates the capabilities of a low-cost, benchtop WDXRF spectrometer for rapid quantitative elemental analysis of cement raw meal.

Dispersion of materials using ultrasound

ultrasound is one of the cleanest, cheapest and most efficient ways to disperse particles and materials into solvents or water. The mixing of powders into liquids is a common step in the formulation of various products, such as paint, ink, shampoo, beverages, or coatings and more recently graphene and carbomb nano tubes (CNTs) and even the hydration of cement for the construction industry.

Calibrating XRF spectrometers for cement analysis

To use X-ray fluorescence analysis (XRF) quantitatively, the analytical system must be calibrated. The usual procedure begins with the purchase of reference materials as powders. These samples are prepared as, e.g., fusion beads, they are measured as calibration standards and, finally, calibration and validation are conducted. Depending on the user’s experience level, the entire method development procedure is more or less cost and time intensive. FLUXANA has spent a great deal of time with the task of reducing these costs and, thus, also the development time for the user. The results are “ready-to-go” calibration sets for various industries that have been tested and approved by laboratories wordlwide. They include different types of calibration standards based on the need of the customers, validaton samples, drift monitors, sample preparation kits and onsite calibration. The flexibility and long-term stability make those calibration sets an ideal solution for highest quality XRF analysis.
