Electromagnetic radiation detection from cubical mortar sample and its theoretical model
Electromagnetic radiation (EMR) signals have been detected from cubical cement mortar specimens during quasi-static compression and impact loading. In case of quasi-static compression EMR voltage vary from 45 to 13 mV while for impact height of 18 cm EMR voltage was found to vary between 434 and 228...

description | Electromagnetic radiation (EMR) signals have been detected from cubical cement mortar specimens during quasi-static compression and impact loading. In case of quasi-static compression EMR voltage vary from 45 to 13 mV while for impact height of 18 cm EMR voltage was found to vary between 434 and 228 mV. Nature of variation of EMR voltage and evaporable water content with increase in number of curing days is observed to be similar. Based on the EMR signals obtained during repetitive impacts mathematical model for EMR under impact loading is presented. Ions contained in the capillary and gel pores of the cement form dipoles and vibrations of dipoles under impact has been considered as the possible source of the observed emissions. EMR signals obtained using proposed model are in good agreement with the experimental ones in terms of nature as well as in amplitude and can be used for deformation monitoring. |
