Concrete slabs and floors can be excellent subfloor surfaces for tile and other floor coverings but too much moisture in the concrete can cause problems with flooring installations In addition it may be necessary to conduct these test several times over the course of weeks as the condition
Corrosion monitoring is the practice of measuring the corrosivity of process stream conditions by the use of probes which are inserted into the process stream and which are continuously exposed to the process stream condition Corrosion monitoring probes can be mechanical electrical or electrochemical devices
It has been used in monitoring concrete hydration and damage detection in RC structures in embedded as well as surface bonded condition Apart from the EMI technique the piezo based materials like piezoresistive cement has also been used to monitor strains in the RC structures under static and cyclic loadings [12] [23]
The ability of devices to detect all CBRN agents is an illusion Therefore it is essential to identify which variables should be detected and organize accordingly the Personal Protective Equipment (PPE) Chemical Biological and Radiological Detection Identification and Monitoring Equipment (for personnel boundary monitoring and analysis)
