To the Question of the Cement-Polymer Composite Materials' Rheological Properties

摘要

The domestic and foreign production polymers effects studies' results on the cement-polymer test rheological indicators are analyzed, taking into account the composition of the functional groups of water-soluble polymers and the viscosity of their one-percent aqueous solution. The rheological studies' results of the Yunis Granit bonding material for fixing the large-format slabs of natural stone and porcelain are presented. The Ostwald, Bingham and Barkley-Herschel equations are considered to describe the flow of pseudoplastic, viscoelastic and rheological complex bodies and their disadvantages. The formula for calculating the rheological parameters: the flowability and the dilution coefficient of nonlinear visco-plastic bodies is proposed and verified. It is shown that the proposed formula describes the structural-mechanical properties of nonlinear visco-plastic systems with a high correlation coefficient.
