Pore size restrictions on polymer load and molecular weight in impregnated cement pastes

Mikhail, R.Sh. / Mousa, A.M. / Abo-El-Enein, S.A. / Marie, M.S.

AbstractThe polymer load was obtained for various PIC pastes impregnated with polystyrene and polymethyl methacrylate. The effect of some structure-forming conditions of pastes on polymer load was investigated, and these conditions include the fineness of the cement, and W/C ratio and the age of the paste. The variation of the polymer load with sample age is explained on structural basis, and the support is gained from SEM studies. Results of the viscosity average molecular weight of the polymer inside the pore system are also presented, showing their dependence on pore size.
