Image Analysis of Surface Porosity Mortar Containing Processed Spent Bleaching Earth.Image analysis techniques are gaining popularity in the studies of civil engineering materials.  However, the current established image analysis methods often require advanced machinery and strict image acquisition procedures which may be challenging in actual construction practices.  In this study, we develop a simplified image analysis technique that uses images with only a digital camera and does not have a strict image acquisition regime.  The properties of mortar are evaluated with flow table test, compressive strength test, water absorption test, and surface porosity based on the proposed image analysis technique.  The quantified image analysis results show accurate representation of mortar quality with 20% PSBE mortar having the lowest porosity.
