Abstract: In this paper, the control equation of nano flow in the C-S-H nanoparticles clusters was proposed. Relatively realistic simulation of nano flow in C-S-H nanoparticles was studied based on theoretical analysis and test results of AFM (atomic force microscope). Two related parameters of viscosity coefficient and slip length were analyzed. At the meantime the influence of van der Waals force generated by the C-S-H nanoparticles clusters was taken into account, the physical model of fluid flow in the C-S-H nanoparticles clusters has been built finally. The study has found that the nano flow in the C-S-H nanoparticles clusters cannot be neglected. The fluid can exchange freely in local part. And the exchange in local part may result in the interaction of C-S-H nanoparticles and affect the shrinkage behavior of cement-based materials.
