The study solves actual modern problem for obtaining polysilicate solution (as a mineral component of clinkerless binder) based on low-quality siliceous raw materials. A mechanochemical synthesis method of sustainable colloidal silica sol (with a particle size of 5-25 nm) is proposed, as well as a grounded choice of grinding parameters is made. Influence of protolytic properties of liquid phase on dispersion speed, aggregate and sedimentation stability of the silica sol are studied. The obtained dependence of the ...

The results of experimental research of hydration process of highly dispersed systems based on saponit-containing waste, extracted as the solid phase of the recycled water suspension kimberlite ore enrichment process of the diamond industry. Saponitcontaining sludge was dehydrated and subjected to mechanical activation on the planetary ball mill. Mechanical activation of raw material more than 60 minutes does not increase the specific surface area of samples was found. Specific surface area is achieves the maximum...

The aim of this three-year study was to determine the effect of different vineyard vegetation cover on organic matter content in the soil, the content of available nutrients and essential soil properties. Soil samples were taken from between rows of vines, where species-diverse mixtures for planting vineyards were sown. For observation, three localities of the Czech Republic with different soil and climatic conditions were chosen (Popice, Mikulov and Znojmo). Two variants of vineyard greening mixes were establishe...

Previous researches have shown the possibility of using organic-mineral additive based on glyoxal for injection strengthening of soils in roadbases and engineering communications. Saponite containing material was used as mineral component in the composition. Saponite containing material is a solid phase, extracted from the circulating water suspension of the kimberlite ore dressing. Modification of the sandy soil by the tailored organic-mineral additive content increases its specific cohesion up to 50 times. It wa...

This paper presents macro- and micromorphological, mineralogical and physicochemical characteristics of solonetzic processes that developed within a 14-cm-thick plough (P) layer of non-ameliorated Solonetz over a 50-year-long period of its post-agrogenic evolution. These processes have resulted in the formation of a microporofile with micromorphological features of eluvial-illuvial differentiation within the former plough layer. The mineralogical analysis of particle-size fractions (?1, 1?5, 5?10, >10 ?m) of the p...

Synthetic polymers play an important role in the agricultural use as structural materials for creating a favorable environment for plant growth. Over the last few years the science of synthetic polymers has received great interest as one of the most exciting areas of polymer chemistry for the production of improved materials. The creation of multifunctional materials with prognosticates properties is important. The main objective of the research was to develop methods for the preparation of transparent hydrogels f...
