Spatial Distribution of Mechanical and Electrical Properties of Cement Mortar Prior to Loading
نویسنده
چکیده
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. © 1998 Elsevier Science Ltd

Different mineral admixtures of Indian metakaolin, Iranian silica fume and nanosilica were used to produce high performance mortars. Two different sands types with grain size of 0.015-4mm were mixed with type II Portland cement, polycarboxylate superplasticizer,mineral admixture with 650kg/m3 cement content and water/cement ratio of 0.35. Different amount of cement was replaced by metakaolin or...

Herein, the performance of graphene oxide (GO) in improving mechanical properties and subsequently reducing the permeability of cement composites used in concrete pavement, is studied. A polycarboxylate superplasticizer was used to improve the dispersion of GO flakes in the cement. The mechanical strength of graphene-cement nanocomposites containing 0.1–2 wt% GO and 0.5 wt% superplasticizer was...

متن کاملPhysico-Mechanical Properties of Organo-Modified Bentonite Reinforced Cement Mortars
It is demonstrated that the addition of organo-modified Na-bentonite (OMB) particles to Portland cement mortar can promote its physical and mechanical properties. A series of experimental works on some important physico-mechanical properties of Portland cement mortars mixed with various dosages of hydrophobic OMB were performed. The obtained results confirm that the OMB provides a dense packing...
