electrical resistivity of concrete

Electrical Resistivity of Concrete

The use of electrical resistivity method for quality control and evaluation of concrete durability is becoming very popular among scholars and engineers. The measurement of electrical resistivity of concrete provides useful information about the microstructure of concrete material. The test procedure has since been standardized by AASHTO TP 95. This method is adapted by several Department of Transportation Read more about Electrical Resistivity of Concrete[…]

Thickness Measurement of Concrete

NDT of Thickness Measurement for Concrete

This articles reviews some of the most accepted and widely used nondestructive tests of thickness measurement for concrete elements. Thickness measurement can be of interest for engineers and technicians involved in the assessment of existing concrete elements, such as slabs, foundations, or pavements, or as a means of quality control (QA) in the construction of Read more about NDT of Thickness Measurement for Concrete[…]
