Claim:
A slurry rheology modifier kit, which comprises a modifier comprising separate and isolated composition (I) and composition (II): Composition (I): comprising a first water-soluble low-molecular compound referred to hereinafter as compound (A) and not comprising a second water-soluble low-molecular compound referred to hereinafter as compound (B), Composition (II): comprising compound (B) but not comprising compound (A); and compound (A) and compound (B) having the following Necessary Conditions 1 and 3: Necessary Condition 1: a combination of compound (A) and compound (B) is selected from (1) combination of a compound selected from amphoteric surfactants and a compound selected from anionic surfactants, (2) combination of a compound selected from cationic surfactants and a compound selected from anionic aromatic compounds and (3) combination of a compound selected from cationic surfactants and a compound selected from NaBr, KBr and HBr, Necessary Condition 3: the amphoteric surfactant is at least one selected from dodecanoic acid amide propyl betaine, octadecanoic acid amide propyl betaine and dodecyl dimethyl aminoacetic acid betaine, the anionic surfactant is at least one selected from POE (3) dodecyl ether sulfate, POE (2) dodecyl ether sulfate and POE (4) dodecyl ether sulfate, the cationic surfactant is at least one selected from alkyl (C 10-26 ) trimethyl ammonium salt, alkyl (C 10-26 ) pyridinium salt, alkyl (C 10-26 ) imidazolinium salt and alkyl (C 10-26 ) dimethyl benzyl ammonium salt, the anionic aromatic compound is at least one selected from salicylic acid, p-toluenesulfonic acid, sulfosalicylic acid, benzoic acid, m-sulfobenzoic acid, p-sulfobenzoic acid, 4-sulfophthalic acid, 5-sulfoisophthalic acid, p-phenol sulfonic acid, m-xylene-4-sulfonic acid, cumene sulfonic acid, methyl salicylic acid, styrene sulfonic acid, chlorobenzoic acid and a salt of the before mentioned acid, and said modifier further comprising a dispersant selected from the group consisting of lignin sulfonates and derivatives thereof, oxycarboxylates and polyol derivatives, naphthalene-based water-reducing agents, melamine-based water-reducing agents, polycarboxylic acid-based water-reducing agents, and polycarboxylic acid-based surfactants, wherein said composition (I) and composition (II) are aqueous solutions having a viscosity of 100 mPa·s or less at 20° C.
