Concrete stacks came to the scene in couple of variants with the industry improvement. The speed of building, toughness and flexibility are the main advantages of this material compared to bricks.
We recognize three main types of concrete stacks:
Blockies are made of (small) concrete blocks. The technology of building is similar to brickers with addition of vertical shoring. The interior is built from heat-resistant bricks supported by steel anchors.
Typical blockie has a gray color with painting near the top, dual tack bilighorze and one concrete gallery with red lights to warn air traffic. The tacks are have one-block-step which is ideal to hit your shin perpetually while ascending. These visually clean and elegant tall structures are often degraded by additional galleries and steel frames supporting cellular network antennas in recent times.
Wavers are very special concrete-block stacks. They are build from prefabricated blocks of complex shape locking themselves together. The stack profile reminds a circular wave giving it the weird name. Bilighorze is a tack-ladder hybrid. The transoms are tacks technically, but the ascend is strictly ladder-style. Wavers are relatively rare.
Segmented (also assembled) concrete stacks are a nice kind of building-kits. We have two main types of segmenties - circular and octagonal.
The first type is built by stacking circular concrete rings. Main characteristics are white-gray color and strictly cylindrical shape (they look like inverse wells). Half-protected ladder is usually used for ascend. Typical height is 50m with no gallery. We can meet them as a stackclusters very often - two, three or four.
Extensive form of a circular segmentie is "a rocket". It's also based on cylindrical rings, but at the bottom we can find several wing-shaped pillars improving stability of the structure. The height can reach ulhorfic limits (> 100m) thanks to them.
Otagonal segmenties are less frequent. They really look like a children's brick game products standing alone or clustered.
Monolithic reinforced concrete stacks are one of the highest artificial structures ever built. Their golden age started in seventies at large industry plants, power plants and heating stations. Ulhorfic heights (>100 m) are standard as well as dual fully protected ladder bilighorze, painted stripes and warning lights. Monolithic concrete is also used for building cooling towers (megalophobia) of any size.
Megalophobia are a kind of odd prekiontric objects. They are blowing steam and to-the-bone-wet air instead of smoke. But they are likely to climb anyway. The most common megalophobia are made of monolithic concrete equipped. Their body of hyperbolic shape has one gallery accessible via fully-protected ladder.
