Abstract

Techniques for analyzing components of hardened concrete and studying its physical characteristics are reviewed. The methods include: light microscopy, wet chemical analysis, X-ray diffraction and fluorescence, absorption spectroscopy (ultraviolet, visible and infrared), electron microscopy, and crack analysis. The scope and problems of each method are discussed. Five examples of routine analyses using these methods individually and together are presented.
