In this paper, the possibility of proportioning self-compacting concrete with high volume calcareous fly ash (W) for precast elements has been investigated. So far, numerous mix design methods for self-compacting concrete have been developed, so as the most appropriate method in this investigation, the UCL method was chosen. In the first phase, the...

Final product of the cold forming process gain many advantages that are mostly produced by strengthening of the material in the process. Those advantages are primarily explained as improving mechanical characteristic of the work material. Because of the effects of strengthening and as one of the specific methods of forming rotationally symmetrical ...
