Technical Information Shore A Hardness 30–50, unswollen (7 d / +23 °C / 50 % r.h.) | (EN ISO 868) |
Change of volume Time | Demineralised water | 5 % saline solution | 1 day | ~25 % | ~8 % | 7 days | ~100 % | ~25 % | 30 days | ~200 % | ~50 % |
Note: In a totally dry state, the Product shrinks to its original dimensions. The product then expands again upon further contact with water.
Swelling pressure The pressure developed by the material depends on the stiffness of the surrounding concrete structure, which is influenced by the concrete quality, voids, gaps and other weaknesses. In an ideal concrete structure the material can develop a swelling pressure up to > 10 bar.
