Calcidur NHL 2 Composition CALCIDUR NHL 2 is a natural hydraulic lime acc. to EN 459-1. It is produced through burning and staking a specifically selected shell limestone. The stabilizing process of CALCIDUR NHL 2 is effected through carbonation and hydraulic hardening. CALCIDUR NHL 2 is free from cement! Properties historic, cement- and gypsum-free natural hydraulic binder high sulfate resistance low-tension hardening process very good subsequent hardening properties no penetration of damaging salts into the masonry high elasticity and water retention capacity in mortar produced very good side adhesion at stone low elasticity module Application For the production of plaster- and brick mortar in ecological,biological building construction, in the restoration and preservation of historic buildings. Storage Dry, if possible on wooden shelves and protected against draft. Technical data Bulk density: approx. 0.5 kg/dm3 free CaO: approx. 35% SO3: approx. 0.4 % Compression strength ( acc. to EN 459-2): 28 days: approx. 4.0 N/mm2 6 months: approx. 6.5 N/mm2 12 months: approx. 8.5 N/mm2 Safety instructions CALCIDUR NHL 2 reacts strongly alkaline with water, thus: Protect skin and eyes, rinse thoroughly with water in case of contact, immediately contact doctor in case of eye contact. Quality-monitored production CALCIDUR NHL 2 is continuously tested in our plant laboratory within the scope of our in-house monitoring with respect to the fulfillment of composition and properties. This will ensure a uniform quality of the product. CALCIDUR NHL 2 has the quality certificate Building lime? and is certified acc. to EN 459-1.
