Abstract:

Comb-shaped hyper-branched polycarboxylate admixture polymers, both the water-reducing-type JS and slump-retaining-type BT, were prepared, and their adsorption characteristics with Ca2+ ions were studied by conductivity loss experiments. The results indicated that, both the water-reducing-type JS and slump-retaining-type BT, would generate certain electrical conductivity loss in CaCl2 aqueous solutions, suggesting that there was some close adsorption between the polymer and Ca2+ ions, the adsorption was closely related with the pH value of the polymers, the neutral and alkaline samples neutralized by NaOH show an higher adsorption than that non-neutralized. The adsorption was achieved by the strong interaction between carboxylic acid groups in the polymer backbones and Ca2+ ions (rather than Cl- ions)
