Shrinkage in Concrete

[Subject Prev][Subject Next][Thread Prev][Thread Next]

I have a project for a foundation that will need to be pumped due to lack of
access.  A big concern of the equipment supplier is shrinkage of the
concrete and achieving tight tolerances for the placement of the concrete.
What all can I do to eliminate shrinkage in a pumped concrete?  Type 5
cement? shrinkage reducing admixtures?  Super plasticizer?  Any other ideas?
