A method of preparing calcium silicate hydrate granules by reacting crystalline and optionally amorphous silica or materials containing the same with calcium oxide or materials containing the same by homogenising them in water, moulding, autoclave curing, comminuting, drying and classifying, the homogenisation being performed by dispersing the solid starting materials in water while adding an anionic surfactant that has previously been converted in water into a microporous stable foam, wherein the homogenised mixture is filled, to a maximum depth of 60 cm, into moulds which are at least 5 square meters in area; a product obtainable by this method and its use in animal litter.
