Long-term resistant construction-material mouldings

摘要

The invention relates to long-term resistant construction-material mouldings which have in particular a sheet-shaped design and comprise the hydration products of a cement or a cement-like binder and alkali-sensitive reinforcing materials, in particular lignocelluloses. To maintain the increased strengths provided by the reinforcing materials, even during the customarily required lifetime, a binder system is used which causes, in the construction material, an alkaline buffer capacity which, 24 hours after the time of production, does not exceed 0.005 acid equivalents/100 g of construction material in a defined aqueous test suspension.
