What could be the damaging impact OF HIGH STRENGTH CONCRETE especially in water retaining structures like dams and spillways.It has been observed that designers mostly propose external 1 meter layer of such structures of high strength concrete as compared to inner one. One of the obvious reason is to ensure economical design and to avoid thermal cracking .High strength concrete provides long term durability ad effective resistant to abrasion. But the worrying point is such kind of difficult arrangement in a reinforced pier cause delay in the progress as well as require special form work. I am searching for some relevant references that describes the negative impact of using high strength concrete.
