Efficiency of Micro-Wave Treatment of Clay Compositions when Selecting the Charge in Technology of Ceramics
Results of the study of microwave treatment of clay compositions with the UHF field when selecting the charge on the basis of low-melting loams of Kalininskoye and Khlystovskoye deposits and a modifying component are presented. The influence of the treatment of the clay composition with the UHF field on the strength property of burned products is shown. Compositions on the basis of galvanic sludge containing derivatives of aluminum oxide and additives containing derivatives of calcium oxide and magnesium – chalk and cake – waste of soda production were tested as a modifier. At the specified ratio of components for each composition of the modifying agent after the treatment of the prepared composition with the UHF field it is possible to obtain the significant improvement of strength of burned samples. Using the method of thermal and X-ray phase analyses, the difference in behavior of masses treated and untreated with the UHF field for compositions on the basis of Kalininskaya clay is shown. The connection of increasing the strength of burned samples with an increase in the fraction of a phase of sillimanite Al2SiO5 and the decrease of the crystallite size up to 30 nm is noted.

Keywords: clay compositions, alumocontaining galvanic sludge, chalk, cake – waste of soda production, UHF field, strength of burned products.

Principles for Creation of Optimal Structures of Ceramic Semidry Pressed Brick The principles for creation of optimal structures of ceramic semidry pressed brick are formulated. It is found out that for low- and moderate-plasticity clay raw material its refinement to class -0.3+0 mm is required. Best grain packaging of the grinded fine raw material during compaction is achieved due to its preliminary aggregation. It is established that the rational granulometric composition of a press powder is ensured by material granulation in the turbo impeller mixer-granulators. Experimentally and in the industrial conditions it is confirmed that the bricks produced from fine grinned granulated material have a uniform, defect-free texture of s ceramic crock, providing an increase (in 1,3–1,5 times) in physical and mechani cal properties of products. A new method for obtaining an effective wall ceramics with uniformly distributed system of freeze resistant macropores incorporated into the wall waterproof glass crystalline framework formed on their surface is offered.

Keywords: optimal structure, ceramic brick, semidry pressing, granulation, effective wall ceramics.

Interpretation of Asphalt Concrete Properties in Road Pavement The consideration of issues related to asphalt concrete road pavement confirms the fact that the pavement itself and its elements are complex systems. The analysis of road pavement conditions is a multifactor task and these factors, in most cases, have a scholastic character. Currently known methods and technologies for monitoring and control over conditions of road pavement have their own limits of applicability. An integral approach making it possible to interpret main deformation and energetic processes taking place at various stages of the operation of asphalt concrete road pavement is proposed. The approach used makes it possible to diagnose the changes in the functional state of asphalt concrete pavement. Scientific hypotheses about the influence of asphalt concrete porosity on its heat capacity and about the prospectivity of the use of the mathematical model of the cusp catastrophe theory for describing the material creep have been formulated.

Keywords: asphalt concrete, road pavement, operational condition, synergetic properties, bifurcation point.

New Organic-Mineral Additives on the Basis of Peat for Cement Systems The method for synthesizing a new efficient organic-mineral additive for cement systems is proposed. Studies of modes of obtaining the additive under conditions of limited access of air are presented. It is shown that in case of introducing the additive on the basis of peat, produced at 600 оC, into the cement system, the significant improvement of strength and hydro-physical characteristics of cement stone is achieved. Results of the X-ray structure phase analysis show that the product, generated during the process of peat treatment at 600 оC, contains various phases in the nano-disperse state, including fullerenes and other forms of nano-carbon which change the kinetics and mechanism of the interaction of cement with water and subsequently lead to improving the strength, water resistance and frost resistance of the cement stone.

Keywords: additives, cement, thermal activation, dispersion, strength, peat, nano-disperse.
