Nuclasit 2.4

Radiation protection mortar for filling openings of cable and pipe penetrations in floors and walls, also suitable as filling material for door frames. To be used in nuclear installations, reprocessing plants and plants with radiation protection requirements in accordance with radiation protection regulation (StrlSchV) and Roentgen regulation (RöV).

Tested and approved according to national and international standards as e.g.:
DIN V 18580 and DIN EN 998-2, other standards on request

One-component, hydraulically hardening; applied by spraying, pressing and manual installation; free from fibres, phenols and halogens, aging resistant.

No radiation-induced damages of serious kind determined according to irradiation table (stage 3 and stage 4) during the irradiation with gamma-rays.

Attenuation measurements accomplished at insulating boards made of mineral mortar NULASIT 2.4 (plates 55 x 55 x 5 cm). The shield effect of the insulating boards is comparable with Barite concrete with a density of 3.5 g/cm³.

The determined pressure resistances according to DIN 18550 of unirradiated and irradiated radiation protection mortar NUCALSIT 2.4 is comparable.
