Compressive Force - an overview ScienceDirect Topics

You can create compressive force by using prestressing steel strands or bars. When this is done, there must be adequate anchorage and you have to be sure that the compressive force will not adversely affect other portions of a concrete member. Cracks found in slabs on grade can sometimes be repaired with steel plates.
