Abstract (en)

[origin: WO2022012928A1] The present invention relates to calcium-containing, porous, mineral materials having a sulfate content of not more than 1.5% by weight and a biopolymer content in the range of 0.001 to 5.00% by weight, each relative to the total weight of the materials, a method for producing these materials with the aid of biopolymers as stabilizers and the use of biopolymers for producing sulfate-poor calcium-containing, porous, mineral materials.
