摘要:
The present invention relates to a dry mortar panel (1) having at least one dry mortar layer (3), wherein the dry mortar layer (3) has a dry mortar mixture that is solidified by means of a water-soluble adhesive, wherein the dry mortar mixture consists of a mineral, in particular hydraulic binder, aggregate and where necessary at least one additive and/or at least one admixture, and wherein the dry mortar mixture has 5 to 35% by weight, preferably 10 to 25% by weight lightweight aggregate comprising open-pored and/or closed-pored lightweight aggregate grains (14) in relation to the dry mass of the dry mortar mixture, and to a method and a device for producing the dry mortar panel (1).
摘要:
The invention concerns mineral, hydraulic binder in powder form, based on a calcium sulphoaluminate-clinker powder containing as admixture at least one activator component acting as an alkali in an aqueous medium for the hydraulic reaction of the calcium sulphoaluminate of the clinker powder, and at least one zinc component which releases zinc ions in an aqueous medium, and preferably at least one setting retardant for the calcium sulphoaluminate, for example at least one setting-retarding fruit acid and/or at least one setting-retarding polyphosphate. The invention further concerns a hydraulic dry mortar, fresh concrete and hardened concrete containing this binder.
