Behavior of the refractory concrete and determination of surface and internal degradation level during the testing were monitored by ultrasonic measurements and image analysis.
It was one of the concrete determinations that helped guide that project that sometimes you just watch the music get made, and you don't need to bring a bunch of interference or concept or a large apparatus to bear".

Reinforced Concrete (RC) buildings can require the determination of in situ concrete strength during the execution of new structures to investigate low-strength results from acceptance tests and, especially, in the capacity assessment of existing structures.
One of the most important features in design of pretensioned concrete elements is the determination of correct transmission (transfer) length.
One of the existing non-destructive methods of determination of concrete resistance to the chloride ion penetration is the surface electrical resistivity by Wenner 4-probe device.
This paper deals with the development and the validation of an innovative, easy-to-use and on site technique for determination of concrete water content.
The article describes the developed methodology and installation for the experimental determination of concrete mixture pressure on the vertical formwork panels.
The determination of concrete resistivity via the Wenner probe has become an established non-destructive technique either as to verify performance based concrete quality or to assess the chloride diffusivity of existing concrete structures.
Finally, this paper concludes that the time-dependent reliability analysis by using gamma process is necessary because of its guidance in the optimization of mix design and determination of concrete cover depth which can further satisfy the durability design of RAC structures.
