Additional Content

Glossary

Resin- or polymer mortars or concrete Mortar and concrete compositions based on organic binders only, i.e. excluding any inorganic binder. In patent literature these terms are sometimes used for compositions also containing an inorganic binder, e.g. Portland cement. If this is the case classification should not be made in this main group but in main group .

Limiting references
