Our short fibres made from alkali resistant glass are very successful at preventing shrinkage cracks in the casting of concrete. They are always used when there is a special danger of cracks, e.g. when concreting over an already hard concrete or with large castings of very fine-grained mortar. In thin-walled workpieces, they also increase the load-bearing capacity.

Fibres are available in D12 and I13 variants. These here are of the type D12, where the letter D stands for "dispersible" and 12 for a fibre length of 12 mm. The word "dispersible" as used herein means that the fibres are grouped into bundles which dissolve into single fibres with the addition of water. After preparing, the concrete is then interspersed with hair-fine glass fibres. The advantage of this variant is that you do not perceive the fibres in the concrete later, even if you then process the surface abrasively. However, only relatively small amounts of this type of fibre can be added into the mix, because fibre balls form when you stir in too much of it. Recommended dosage maximum 0.5% of the concrete weight

By the way, dispersible fibre type D12 is also very popular in order to make self-compacting concrete so stiff that it can be smoothed over. This trick allows thin-walled negative laminating into moulds with high-strength concrete. Try the technique with our STEINGUSS.

In our online shop you buy glass fibres only from renowned manufacturers, in small quantities at a reasonable price.
