I hypothesize that one of the reasons the yarn performed so much better than the deer net is because it is more permeable and thus formed a better bond with the concrete.
In this scenario, I would imagine that it would be "locally tensioned" because the cement is effectively tightly bonded across any point of stress. Would be an interesting experiment!
Isn't the point of pre-tensioning is not the actual tension on the reinforcement, but the pre-loading of the concrete - so it needs to happen everywhere in the volume of the concrete, not just next to the reinforcement?
Interesting point; I see what you are saying like during the curing process, the tension in the yarn weave itself would pre-tension the dried slab. But I wonder if acrylic yarn would have a sufficient effect and to what extent.
If anyone has science fairs coming up, these seem like excellent experiments!
