Anhydrite or anhydrous calcium sulfate (CaSO4) is an important naturally-occurring compound found in many limestone formations and karst topography. This material has recently gained more significance to the cement industry as a substitute for gypsum—calcium sulfate dihydrate (CaSO4·2H2O). Anhydrite shows great efficacy as a cement setting retardant. This allows valuable time for other phases to form which enhances the cement’s tensile properties.
“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”.

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….
“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…
Recycling has become a term that cannot be ignored in the industrial world. Recycling is roughly classified into (1) “re-use”, utilizing something again for the same purpose, (2) “material recycling”, returning something into the original material for subsequent use, (3) “chemical recycling”, changing something into another material for subsequent use, and (4) “thermal recycling”, using something for thermal energy. New technologies utilizing fly ash of urban refuse as cement material (chemical recycling) and converting urban refuse into solid fuel (thermal recycling) have attracted a lot of attention. In X-ray fluorescence (XRF) analysis, it is possible to perform qualitative and quantitative…

Wood treatments are used to protect lumber from fungi, insects, UV damage and general wear. Lumber treated with copper or copper oxide is used in a variety of residential and commercial construction projects, including house and building foundations, fences, patio decks and playground playscapes. When treating wood, the proper balance of treatment solution must be monitored to ensure the highest quality while minimizing waste and excess cost due to treatment usage or product rejection. Cu or CuO levels are monitored in solution prior to treatment, and then in the wood to ensure proper retention. A quick, simple, reliable means of…
Wood treatments are used to protect lumber from fungi, insects, UV damage and general wear. In recent years, the US EPA has asked for voluntary compliance to restrict the use of chromated copper arsenate (CCA), due to concerns of Cr and As leaching into soils, Lumber treated with CCA is used in a limited number of situations, such as in roofing shingles, permanent building foundations, and certain commercial applications. When treating wood, the proper balance of treatment solution must be monitored to ensure the highest quality while minimizing waste and excess cost due to treatment usage or product rejection. Cr,…
Electric arc furnace steelmaking, also called EAF, typically uses Direct reduced iron or ferrous scrap as the feed materials. In the electric arc furnace lime (calcium) is added to remove silicates and phosphorus. With the addition of oxygen the ferrous materials are essentially melted, while the remaining material is changed to oxide forms. The slag by-product, also called EAFS, contains relatively constant levels of these oxides and variable amounts of iron, calcium and silicon oxides. Monitoring the FeO levels indicates the efficiency of the process, while monitoring the ratio of CaO to SiO2 gives information on the basicity of the…
Building materials play an important role in today’s industry. Their composition has a big influence on material properties and fields of application, as well as on their behavior in ecosystems and recyclability. Tightly monitoring the elemental composition of building materials, such as cement, is key for ensuring their quality, and this composition is thus routinely measured in industrial quality control labs.
Urea is an organic compound that plays an important role in biological metabolism processes. Besides its physiological properties, synthetically synthesized urea has become a very meaningful compound in the clinical, pharmaceutical, and chemical industries. It is a starting material for the synthesis of a large number of chemicals including hydrazine and melamine that are further used for the production of resins eventually used as building materials. In agriculture, urea is a preferred compound to be used as fertilizer because of its high nitrogen content. Another application with constantly rising importance is it use as an active ingredient in exhaust gas…
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.
It’s a key safety and legal requirement to deterin the calorific value / energy content of any materials used in the construction and buildng industry. When the worst happens and a building catches fire, companies want to minimise the ferocity that the materials burn with. Parr calorimeters are used for testing new building materials to be used in future construction and also the content of waste material after demolition. This is the key criteria for the fire safety testing industry.
Calorimeters are a crucial tool in the analysing the energy content contained in waste solvent and other waste like buildng mateirals and municiple waste. The total energy content can be determined by the Parr range of calorimeters.
In the cement industry, x-ray fluorescence analysis (XRF) is one of the major techniques employed for raw material and final product quality control. Typically, “pressed pellet” sample preparation is used; however, the disadvantage to this is that this technique shows only relative data to known and accepted reference methods like fusion or wet chemistry and takes no account of the different mineralogical effects that may or may not occur. The FLUXANA VITRIOX ELECTRIC uses borate fusion to eliminate these negative effects and achieve high accuracy in XRF analysis. Fusion removes particle size effects and creates homogenious samples with perfect surfaces….
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…
