Placement Method for Expansive-Cement Concrete

We're placing our first bridge deck with shrinkage-compensating concrete using Type K expansive cement. We normally use a crane and bucket for bridge decks but wonder if this is the best placement method for shrinkage-compensating concrete.

What is effect of silica and alumina content on cement ...

On cooling, expansive ettringite formation takes place. Because they are even more basic, the alkali-loaded polymorphs are correspondingly more reactive. Appreciable amounts (>1%) in cement make set control difficult, and the cement becomes excessively hygroscopic. The cement powder flow-ability is reduced, and air-set lumps tend to form.
