Abstract

Comparative study on the dispersing performances of polycarboxylate superplasticizer (PCE) in cement pastes prepared with deionized water and seawater was conducted by involving techniques of fluidity tests, measurement of adsorption amount of PCE, isothermal calorimetry, X-ray diffraction and specific surface area analysis etc. It is shown that the seawater leads to a visible drop of the initial fluidity of the PCE plasticized cement paste and faster loss of the fluidity over hydration time, compared to deionized water. Mg2+ ion present in seawater reduces the dispersing efficiency of PCE in fresh cement paste (fcps) due to the possible complexation between Mg2+ ions and PCE. SO42− ion present in the seawater notably promotes the initial formation of AFt crystals and increases the specific surface area of fcps, which consequently consumes a large amount of PCE molecules and results in a faster fluidity loss over hydration time.
