Recently, it has been proven that the casting technology is advanced because the slab grinding ratioofgrade 304 is on the same level at the reference plant.
Continuously readjusting the grade limit value(classical domain and joint domain) of every factor can maximize the ratio of historical runoff to actual runoff production in a drainage basin.
It shows the axial tension initial cracking strength of concrete increases with the increasing of steel fiber volume ratio and enhancing of concrete strength grade separately.
