A 3D-printer for working with plastic mineral mixtures is developed, its kinematic scheme and principle of operation are described. The results of experiments on printing simple forms of plastic clay, using a piston-type extruder, are presented. In relation to an additive technology, a list of technological properties of mineral masses is defined The optimal amount of chemical additives has been established, which provides an increase in the uniformity of the raw material mass for printing products from light ceramics.

Studies of the influence of vibration impact on the strength of foam-ceramic raw material, produced on the basis of chemically modified natural silicites, are presented. The natural oscillation frequencies of mineral particles are established, taking into account their size, density and ultimate shear stress of raw suspensions. It is shown that the coincidence of the natural and forced oscillations of the particles leads to an increase in the thixotropic effect. Using the technology of a controlled «sol-gel» transition in the structure of raw material, swelling under the influence of vibration load, samples of the material were obtained with a higher-quality macrostructure without the use of binders. Indicators of compressive strength and average density of raw and ceramics are given.

Hyper-Pressed Composites from Recycling Products of Aerated Concrete Waste

DDF

A technology has been developed for obtaining wall materials by the hyper-pressing method, including the recycling of large-tonnage waste from the production of autoclaved aerated concrete. The main component of the raw mixture is finely ground filler fractions, obtained by crushing substandard fragments of aerated concrete. The joint influence of raw mixture, the parameters of pressing and the conditions of hardening on the indicators of material properties has been investigated. There was given a quantitative assessment of the individual components contribution of the raw material composition to the indicators of the physical and mechanical properties of the material. The mechanism is disclosed of the constructive effect of aerated concrete recycling waste and plasticizing additives on the water resistance and strength of samples. The promising areas of application of hyper-pressed materials in modern construction are presented.
