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

Structural Health Monitoring

Smart Structural Health Monitoring

I would like to start this by a very simple example: that infrastructure facilities work very similar our body. When they are first built (i.e. like when we are at our young age), they operate at their best. Just a routine checkup is all you need to

DETERIORATION OF CONCRETE

Deterioration of Concrete Structures

Deterioration of reinforced concrete structures can happen for a number of reasons. Physical and Chemical processes can impact durability and structural performance of the concrete. Defects in design, materials, workmanship, curing and maintenance can all impact the service life, safety and reliability of an element. In this
