if the concrete contain waste cardboard i think ultrasonic wave will disturb
and give useless values. The best assessment method by using standard cast cubes.
PUNDIT is basically an ultrasonic testing equipment for concrete which measures velocity of ultrasonic wave. Equipment is manufactured by ELE UK.
It give velocity depending of how much concrete is dense and therefore good concrete has high velocity and poor low velocity.
Following up on the previous response, the velocity of the ultrasonic wave can generally be relateed o the modulus of the concrete (and perhaps to strength via further correlations)
In addition, this discussion may be useful to predict compressive strength :

For ur work i think it is not so useful, better use crush test
