The taxi-way system includes the following: 1  A parallel taxi-way 30 metres wide designated P. 2  Link taxiways 30 metres wide marked Q , W , Y & Z. 3  Holding bays at every intersection to the runway.  Loop taxi-ways at both ends of the runways.
Although concrete gains strength more slowly at lower temperatures, the strength of concrete cured at will eventually reach that of concrete cured at 70Â°F. Even if the concrete temperature drops to the mid teens, the hydration process will continue a very slow rate.
Materials Needed to Cure Concrete During Winter. Curing concrete in cold weather can be achieved using different materials depending on the amount of concrete being cured and the surface being protected. These materials when used properly will increase or produce a constant heat of hydration of the concrete. For example: Insulating sheets, Straw-plastic,
