It furnishes step-by-step procedures for processing image data to produce segmentation of an image eld into its constituent mineral phases, and describes ways use the segmented image to measure the abundance, surface area, and spatial distribution of phases in the image eld. Inherent heterogeneity of the microstructure implies that di erent image elds of the same material will contain di erent phase abundances; the document suggests ways to estimate and compensate for the heterogeneity length scale through statistical analysis of multiple image elds. and analysis using a scanning electron microscope will be illustrated using an example from the development of Standard Reference Materials for portland cement clinker. 606 $aBuilding materials industry$xAppropriate technology 606 $aCement 606 $aComputer simulation 615 0$aBuilding materials industry$xAppropriate technology. 615 0$aCement. 615 0$aComputer simulation. 700 $aStutzman$b Paul E$01392797 701 $aBullard$b Jeffrey W$01390864 701 $aPan$b Feng$01399766 712 02$aNational Institute of Standards and Technology (U.S.).$bEngineering Laboratory. 801 0$bNBS 801 1$bNBS 801 2$bGPO 801 2$bNBS 906 $aBOOK 912 $a9910711380703321 996 $aQuantitative imaging of clinker and cement microstructure$94529094 997 $aUNINA
