“…2. For all compositions, the character of the curves of the dependence of the plastic strength on moisture does not change and is expressed by two rectilinear sections that characterize respectively the region of successive development of adsorption films and hydrate shells, and the region of excessive (free) water [24].…”

“…Determination of the plastic strength of elasto-plastic-viscous systems was carried out by Rehbinder's conical plastometer. The method does not contain empirical constants and makes it possible to make measurements at small velocity gradients [24]. The values of fast and slow elastic and plastic deformation were determined on an installation operating on the principle of a parallel-shifting plate (D.M.…”

The purpose of work: the choice of the rational composition of the batch mixture, which improves the molding properties of the silt loams in the production of wall ceramics by the method of plastic molding. In the course of the study, the fraction-size distribution and morphological features of the fractions were analyzed on a photometric sedimentometer FSX-6K and by optical microscopy. Determination of the plastic strength of elasto-visco-plastic systems was carried out by Rehbinder’s conical plastometer. The values of fast and slow elastic and plastic deformations were determined on an installation operating on the principle of a parallel- shifting plate. For molding compounds with various corrective mineral additives, optimum values of molding moisture in which the compound is not adversely affected by shortage and excess moisture have been experimentally established; moduli of fast and slow elastic deformation and other structural and mechanical characteristics are determined. The percent values of the reduced deformations were obtained on the basis of rheological curves of disperse systems in the axes “deformation - shear time”. It is established that the additions of components of different genesis and with different fraction morphology affect the deformation behavior of the molding compounds.

“…For example, the moisture content of a compound can be determined according to the value of the plastic strength [1,6,15,17]. A stamp with a constant cross section is suitable for studying compounds which have a short induction period, for example, molding compounds containing ce- ment [1,16,21].…”

“…Most instruments were developed for performing rapid testing. They are convenient for monitoring the rheological properties directly during production and are quite simple to use [4,7,13,16,17]. In what follows only the methods which make it possible to obtain parameters of compounds that have an unequivocal physical interpretation will be examined.…”

A classification is given for methods of measuring the rheological properties of ceramic compounds for extrusion. Depending on the magnitude of the shear stresses under which the testing is performed, it is proposed that the methods of investigation be divided into structural-mechanical and rheological. The most informative methods as well as the structural-mechanical and rheological parameters obtained with these measurements are described. Recommendations are given for using each method for scientific investigations and for checking the parameters of the molding compounds in the production of extruded ceramic articles.
