Can anyone shed some light or point me in the right direction for obtaining information on the use of greywacke aggregate on the long term durability of concrete. Also whether it will contribute or cause shrinkage cracking of the concrete both in both the short and long term.
Thanks

Trying to find some useful information on the limitations, timescales involved and the actual process of using heat straightening to repair steel beams struck by high vehicle in lieu of cutting out and replacing damaged rolled steel sections?
Any clues/tips??
