Interior with the Pantheon dome, seen from beneath. The concrete to the coffered dome was laid on moulds, mounted on non permanent scaffolding.
Concrete that may be partially combined in the plant mixer and afterwards discharged into the drum in the truck mixer for completion with the mixing is known as shrink mixed concrete.

Just about every bag have to be pierced by a minimum of one, and ideally approximately 4 pins. Bagwork is a straightforward and convenient means of underwater concrete placement which will not require pumps, plant, or formwork, and that may minimise environmental outcomes from dispersing cement in the drinking water. Prefilled bags can be obtained, that happen to be sealed to forestall premature hydration if stored in suitable dry conditions. The luggage may be biodegradable.[131]
