Furthermore, quantitative characterization of microstructure is an essential input to microstructure-based computer models of cementitious material processing and properties. This document describes the use and operating principles of MicroChar, a computer application for automatically calculating a range of microstructural properties from an indexed 2D image. Among the properties calculated are the volume fraction, mass fraction, and surface area fraction of each phase in the image, as well as two-point correlation functions for quantifying the spatial distribution of the phases throughout the structure. The application also enables the user to package the data obtained on cement powders for uploading to the Virtual Cement and Concrete Testing Laboratory Consortium (VCCTL) software. 517 $aMicroChar 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 $aBullard$b Jeffrey W$01390864 712 02$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 $a9910711380803321 996 $aMicroChar$93443999 997 $aUNINA
