Study the Effect of Springboard on Concrete Performance Containing Low-Carbon Steel Spring

One of the most important parameters in spring resistance and strength of concrete containing spring is its step length. In this paper, by adding a low-carbon steel spring with diameter, a number of steps and various mixing rates to self-compacting concrete, attempts have been made to improve its me...
