The present invention relates to a sack for liquid or pulverulent materials having an areal section (F) composed of a water-soluble polymer, wherein dissolution of the water-soluble polymer gives rise to an opening through which the sack can be emptied, to a sack according to the invention that contains a liquid or pulverulent material, to a method for the emptying thereof and the production thereof, and also to the use of the sack for the packing of liquid or pulverulent materials and to the use of an areal section (F) composed of a water-soluble polymer as part of a sack for liquid or pulverulent materials for the reduction of the release of unpleasant odors and/or harmful substances into the air, especially for the reduction of the release of alveoli-reaching dusts.

Sack for liquid and pulverulent substances comprising a soluble surface portion, method and use therewith, and use of a soluble surface portion

The invention relates to a mixture containing an alkali-activated aluminosilicate binder, said mixture, after hardening, containing at least 25% by weight of glass beads, based on the total mass. The hardened product has a surface which has very little tendency to soil and is easy to clean. A process for the preparation of the mixture according to the invention and the use thereof as joint filler are disclosed.

Alkali-activated aluminosilicate binder containing glass beads

A novel binder system comprising at least one latent hydraulic binder, at least one amorphous silica, optionally at least one reactive filler and at least one alkali metal silicate is proposed. It was surprisingly found that the binder system according to the invention hardens in the form of a hybrid matrix which is acid-resistant, water-resistant and alkali-resistant. The binder system can be used for the production of a hydraulically setting mortar which, after setting, hardening for seven days and subsequent storage for three days in acid, base and/or water, has compressive strengths of more than 15 N mm, preferably more than 20 N mmand in particular more than 25 N mm, according to DIN EN 13888.

Inorganic binder system for the production of chemically resistant construction chemistry products

The present invention relates to building material mixtures which contain slag sand and zinc salts which have from 0 to 8 carbon atoms in their structure. The invention furthermore relates to the use of zinc salts for preventing discolorations during the hardening of the building material mixtures.
