GeneralQ I am trying to find out if there is any research or literature regarding the drying shrinkage of shotcrete. Can you help?
See ACI 506R, Sec. 1.7 (ACI document). Typical shrinkage varies in the range of 0.06 to 0.10 percent after 28 days drying. It is typically slightly higher than similar strength concrete, mostly due to less and/or smaller coarse aggregate in the shotcrete mix.
