ndt for concrete using pulse velocity

Will it be possible to use pulse velocity in relation to concrete compressive strength for shallow foundation?
Is this any research on this?
Can anybody send me a copy of the compilation if there is any, of
the correlation of concrete compressive strenght in relation to pulse velocity?
thanks!

Re: ndt for concrete using pulse velocity Attempts to relate ultrasonic pulse velocity to conrete compression strength extend over more than three decades. Since there is no single physical relationship articles and books have been filled with effects of influencing factors.
There are so many influencing factors that common opinion is now to use such relationships only in very controlled environments as in the fabrication of precast concrete elements.
Descriptions of measurement and correlation methods are contained in European standards prEN 13791 (preliminary) in conjunction with prEN 13296 (preliminary, will be renamed to EN 12504-04), for example.
