Abstract

The hardness was found to be lower (by ∼10 in Rockwell H scale) and the volume electrical resistivity was found to be higher (about doubled) at the edge (up to a depth of ∼5 cm for curing at 100% relative humidity) than at the center of a cement mortar specimen prior to loading. This is attributed to the faster drying at the edge and the resulting poorer bond between cement paste and sand at the edge than the center.
