It is also possible to mix concrete or mortar with a wet or dry process to create a concrete layer of mortar or mortar to which the concrete or mortar is applied. the aqueous suspension of (A) alumina and aluminum compounds selected from the group consisting of wounds of aluminum, cast with wounds of aluminum, alum, and mixtures thereof with this aqueous suspension (A) m pH ni 4. An aqueous suspension has a solids content of between 10 and 50% by weight and, after a rest period of 48 hours, takes the form of a gel which is reversible due to small shear forces. So the water suspension (A) is used as a set for concrete mixes or mortars, especially for layer thicknesses and to reduce the aging of the mass. \ t |
