METHOD FOR MEASURING THE POROSITY OF CONCRETE USING BACKSCATTERED ELECTRON IMAGING TO IMPLEMENT ACCURATE MEASUREMENT ON A POROSITY RANGE SELECTED BY A USER

摘要

PURPOSE: A method for measuring the porosity of concrete using backscattered electron imaging is provided to evaluate the endurance of a concrete structure against harmful chemical ion and to estimate the life span of the concrete structure.;CONSTITUTION: A method for measuring the porosity of concrete using backscattered electron imaging comprises steps of: collecting a concrete specimen, photographing the surface of the concrete specimen using backscattered electron imaging, dualizing the backscattered image, and calculating the porosity of concrete from the dualized image.;COPYRIGHT KIPO 2012
