Sep 15, 2015  Cement–emulsifier pastes for ions concentration measurement were prepared at the ratio of W/C (0.6) and E/C (0% and 0.5%). In order to illustrate the retardation effect of emulsifier on cement hydration by electrical resistivity, the ratio of the paste should keep correspondence with that of the hydration heat measurement.

Effect of emulsifier on cement hydration in cement asphalt ...

Oct 01, 2013  Emulsifier with excessive retarding effect on cement not only abort cement hydration in early age, but also cause a loss in the later hydration heat and content of cement hydrates. Therefore, suitable emulsifier with little retarding effect on cement hydration and its appropriate dosage are recommended when producing asphalt emulsion for CA mortar.

The rate of hydration during the rest of the curing period was critically dependent on the residual w/c which was decisively influenced by the content of emulsifier. The cement could be expected to reach a very high degree of hydration only in mixtures with the highest emulsifier content, considering the specimens as a whole.

EFFECT OF BITUMEN EMULSION ON MECHANICAL

the emulsifier has a retarding effect on cement hydration, which increases with the mass ratio of emulsifier to cement and differs for different emulsifier types [27]. Moreover, it is not eliminated after the emulsion breaking is accomplished, and remains in the binder in some form. Therefore, the emulsifier can be considered as an additional ...
