Figure 20: Concrete strength estimation for slab C1.1 two days after construction using the modified shear wave velocity It should be noted that the maturity and shear wave velocity models developed for the long-life concrete mixture design are only valid for a pavement age of at least 1-day. Using these models to compute strength in the first few hours after paving might predict unrealistic, negative strength estimations.
