USE OF FINELY GROUND CALCIUM CARBONATE IN INORGANIC MORTAR SYSTEM BASED ON ALUMINATE CEMENT TO INCREASE LOAD VALUES

摘要

FIELD: building materials.;SUBSTANCE: present invention relates to the use of calcium carbonate having an average particle size in the range from 0.5 to 3 mcm, preferably from 1 to 3 mcm, in an inorganic mortar system for chemical fixation of anchors and glued reinforcing rods in mineral bases, containing a curable component of aluminate cement A and an initiator component B to initiate the curing process, wherein the component A additionally contains at least one blocking agent selected from a group consisting of phosphoric acid, metaphosphoric acid, phosphorous acid and phosphonic acids, and at least one plasticizer and water, and the component B contains an initiator, at least one setting retarder, at least one mineral filler and water. In addition, the present invention relates to the use of calcium carbonate having an average particle size in the range of 0.5 to 3 mcm, preferably from 1 to 3 mcm, in an inorganic mortar to increase load values, as well as to a method for chemical fixation of anchors and glued reinforcing rods, preferably metal anchors and glued reinforcing rods, in mineral bases, such as structures made of brickwork, concrete.;EFFECT: obtaining an inorganic mortar system.;16 cl, 3 tbl
