Abstract
The hardness was found to be lower (by similar to 10 in Rockwell H sca le) and the volume electrical resistivity was found to be higher (abou t doubled) at the edge (up to a depth of similar to 5 cm for curing at 100% relative humidity) than at the center of a cement mortar specime n prior to loading. This is attributed to the faster drying at the edg e and the resulting poorer bond between cement paste and sand at the e dge than the center. (C) 1998 Elsevier Science Ltd.
