To calculate the lap length-48*D
For calculating hook & bend -As per Is 2502,The anchorage value of the of bend shall be taken as 4*D of the bar for each 45 Degree bend and for the U type hook its always taken as 16* D.
For the bond length(Development Length)-Ld-It is calculated by the formula. and it includes all the values of the anchorages.
X = Cement ,Fine Aggregate & Coarse Aggregate are in taken in weights for batching.
Y= Cement , Fine Aggregate & Coarse Aggregate are taken in volume for batching.
Then what will be the relation between X and Y?
