Other experiments like fluidity test and test of the amount of plasticizer adsorbed on cement particles are also carried out. Results show that SNF plasticizer has different effects on the resistivity of cement pastes comparing with LS plasticizer.

    IntroductionWater Reducing ChemicalsCement plasticizer IncompatibilityModern concretes almost always possess additives, either in the mineral form or chemical form. Particularly, chemical admixtures such as water reducers and set controllers are invariably used to enhance the properties of fresh and hardened concrete.A ‘Chemical Admixture’ is any chemical additive to the concrete mixture that enhances the properties of concrete in the fresh or hardened state. This does not include paints or coatings. ACI 116R [2000] defines the term admixture as ‘a material oth...
