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.
There are three ways to cure concrete: either we add water to the surface to replace the water that is evaporating or we seal the concrete to prevent the water from evaporating in the first place or we do both.et's talk only about horizontal concrete and only about the moisture part of curing. To learn more about working in temperature extremes get a copy of ACI 305, Hot Weather Concreting or ACI 306, Cold Weather Concreting. Let's also narrow things down to curing of colored concrete.
