Cement laboratory specific surface volume tester
Cement Specific surface area is surface area of a sample per gram. The calculation model of specific surface area is BET equation according to physical absorption theory.
BET analysis provides precise specific surface area evaluation of materials by nitrogen multilayer adsorption measured as a function of relative pressure using a fully automated analyzer. The technique encompasses external area and pore area evaluations to determine the total specific surface area in m2/g, yielding important information in studying the effects of surface porosity and particle size in many applications.
