Cobiax Installation and Concrete pouring

[@dipalmehta4313]

Good initiative and informative. Just one question. How to ensure sufficient cover to reinforcement inside as it rest on ball.?

[@timvangool291]

3:50.. Vibrating to long is not good for the concrete mix.. The cement wil float on top and the stones vibrates to deep..

Super.

NOISE TRANSFER ?

[@watchthe1369]

okay don't the bubbles weaken the slab, I do not get the reasons for this.

[@aripocki]

Similar to how concrete plank has holes in it. I'm guessing the X&Y axis are held together by the "cages" as some form of rebar.

[@casek1238]

The reason is: concrete-weight-gain and cost-reduction. But there will be less noise reduction and heat absorbtion and accumulation and possible weaker construction. The new parking garage in Eindhoven collapsed on a very hot day, before it was even in use. I think. the cheese form with site rim of the elements, seems to be much better than the perfect ball form. Because the used plastic does not connect to the concrete.

@@casek1238 is that cobiax technology?

[@casek1238]

@@printpainting1293 I do not know if it is cobiax. I think they used Dutch "breedplaatvloeren" or "bekistingsplaatvloeren" The balls with their smooth surface save concrete, but don't connect to the concrete.

when and where to use cobiax slab design?
