### Compressive Strength Of Concrete Hollow Blocks (formula

Nov 16, 2017 If there is a reinforcing nail or bar in the concrete as it sets, the concrete will shrink around the bar and indoing so will grip the bar very very tightly as shown in the right hand part of Fig6. So the bar is very strongly embedded in the concrete. This embedding is called the bond strength.
