[JFCPEng]

Has anyone access to shrinkage rates correlated to other variables including silica fume and w/c?

DEVELOPMENT OF CONCRETE SHRINKAGE PERFORMANCE SPECIFICATIONS by David W. Mokarem PhD Dissertation

Section 2.4 Influence of Concrete Composition on Shrinkage

My Comments: Water per unit volume is the most important factor. Refer to "Effect of Concrete Ingredients on Drying Shrinkage" in

http://www.cement.ca/cement.nsf/0/2A4A1D82ADCA0FCE852568AB00111731?OpenDocument

and Section 2.4.3 "Influence of Cement and Water Content" in literature survey portion of Mokarem's dissertation.

If you desire shrinkage values for concrete mixtues batched with local materials and ingredients like fly ash, SF, expansive cement etc consult CMT companies in the area. They should have a good idea based on results obtained from trial batches.
