A contribution to the explanation of the action principles of organic plasticizers

Suspensions of laboratory cement modified with 0.25% to 1.5% of MSFC-type dispersant were prepared. The sorption of organic molecules, viscosity and integral value of heat liberation after 5, 10 and 20 min were determined. Regression analysis showed that the viscosity changes of suspension are influenced by about 86% by the changes of sorption and heat liberation.
