Fibres and Proportions
If one were to add fibre to aircrete to add tensile strength, what sort of fibre would be best and in what concentrations? Has there been any testing to that effect?
We tested PVA fibers and it worked great. It was recommended by Steve Kornher of Flying Concrete - http://www.flyingconcrete.com/
Steve does amazing work if you haven't seen it, check it out. He's been working with concrete for decades and recommends PVA fibers. We've tried to get hemp fibers but no luck yet. We prefer to reinforce the surface with poly reinforcing fabric - https://www.apoc.com/products/roof-reinforcements-firm-polyester-reinforcing-fabric-apoc-482f
With surface reinforcement there isn't need for interior reinforcement in our applications.
What do you use the adhere the fabric to the AC?
