Measurement of the chemical composition, phase abundance, and microstructure of cementitious materials is an increasingly important
This workshop will provide practical information and guidance on performing chemical and phase analyses of portland cement and portland cement clinker materials, including hands-on practice with analyzing real data. The workshop will address number of complementary methods but will focus especially on quantitative X-ray powder diffraction (XRD) and quantitative scanning electron microscsopy (SEM) for characterizing unhydrated materials.
- Quantitative X-ray Powder Diffraction (QXRD): Theoretical basis, instrumentation, specimen preparation, measurement artifacts and sources of error, internal and external standards, interpretation, and detection limits.
- Quantitative Scanning Electron Microscopy (QSEM): Theoretical basis, instrumentation, backscattered electron imaging, X-ray microprobe analysis, measurement artifacts and sources of error, image analysis, phase segmentation, advantages and disadvantages compared to QXRD, and microstructure characterization.
- Practicums on QXRD and QSEM: Participants will receive a complete set of cement-related raw material data sets obtained on portland cement powders, and will be given step-by-step guidance on analyzing the data to quantify the chemical composition and phase abundance using freely available software in the public domain.
- Principles and Applications of
- X-Ray Fluorescence (XRF)
- Thermogravimetric Analysis (TGA)
- Surface Enhanced Raman Spectroscopy (SERS)
Who Should Attend
The workshop assumes a general familiarity with concrete materials, but no specialized knowledge of materials characterization is required. Engineers, research scientists, and technicians responsible for cementitious materials characterization, quality control, or testing should find this workshop beneficial for their continuing education and professional development.
