Hardy Slab

Hardy Slab

Hardy slabs are generally seen in Dubai and China. Hardy slab is constructed by hardy Bricks. Hardy bricks are hollow bricks and made up of concrete Hollow blocks. These blocks are used to fill portions of the slab. Hardy slabs saves the amount of concrete and hence the own weight of the slab is reduced. This kind of slab has a more thickness 0.27m when compared with the conventional one.

Where to use Hardy Slab?

uHardy slab is used where temperatures are very high. To resist the temperature from top of the slab thickness is increased. The heat coming from walls are resisted by using special bricks which has thermal in it. Thermal is the best insulator of sunlight.

Advantages of Hardy Slab:

uReducing slab weight by reducing the amount of concrete below neutral axis.

uEase of construction, especially when all beams are hidden beams.

uEconomic for spans > 5m with moderate live load: hospitals, office and residential buildings.

uImproved insulation for sound and heat.

Disadvantages of Hardy Slab:

uIf not properly handled, the hollow core ribbed brick units may be damaged during transport.

uNot economic for small spans.

uDifficult to repair and strengthen.
