Prediction of the Static Modulus of Elasticity Using Four non Destructive Testing

The static modulus of elasticity (Es) is an important parameter in the analysis of hydraulic concrete structures, changes have been made to the regulation of construction; these changes require minimum values for the Es, so now, in addition to concrete compressive strength (f'c) also Es values...
