The article summarizes the results of the survey of the Murmansk archaeological expedition in the Lovozero district from 2019 to 2022. Presented a brief site description of the northwestern coast of the lake Lovozero and the upper reaches of the river Voronya. Seven new archaeological sites dated from the Mesolithic to the Bronze Age were discovered during the four field seasons. The Expedition also localized ten sites discovered in 1969–1974.

The effect of silica-containing additives, obtained by leaching waste magnesium-iron slag from copper-nickel production, on the strength properties of lightweight concrete on porous aggregate has been studied. It has been established that the introduction of SiO2 additives in the amount of 0,5–2,0 wt. % into the composition of concrete increases the strength of concrete at the design age by 15–40 % compared to the composition without additives. The additives also increase the specific strength of concrete up to 38–40 MPa, which makes it possible to classify the developed concretes as high-strength ones (Rud ≥ 25 MPa).

The paper presents the results of zinc precipitation from sulfate solutions with alkaline reagents (serpentinite magnesite and calcium oxide). X-ray diffraction, micromorphological analysis, and thermodynamic modeling revealed the formation of stable metastable silicate zinc-containing phase in the experiment with the use metaserpentine as a reagent. When calcium oxide is used as a reactant, zincite precipitated.

Mg-Al LDH samples of Mg4Al2(OH)12CO33,85HO composition were obtained by solid-phase synthesis. It was found that as a result of heat treatment with subsequent rehydration, synthesized Mg-Al LDH samples are reduced to the composition Mg4Al2(OH)12CO33HO, regardless of the medium and duration of treatment. It has been shown that rehydration in NaHCO3 solutions contributes to an increase in the crystallite sizes of Mg-Al LDH samples being recovered, which is not observed when Mg-Al LDH is reduced in an aqueous medium. An increase in the duration of hydration in NaHCO3 solutions leads to an increase in the crystallites of Mg-Al reduced LDH, which is not observed during rehydration in an aqueous medium.

A comparative analysis of the composition and properties of titanosilicate powders obtained with the use of technogenic raw materials or being production wastes was carried out and their influence on the properties of cement compositions was studied. It is shown that the effectiveness of the action of nanodispersed titanosilicate powders depends on their specific surface area, phase composition, and on the method of introducing nanosized additives into the bulk of the cement matrix. Despite the differences observed in the chemical and phase composition, specific surface, and morphology, they all exhibit photocatalytic activity in the methylene blue decomposition reaction and self-cleaning and bactericidal properties in the composition of the cement matrix,accelerate hydration and increase the strength of the binder.

The paper presents the results of studying the binding properties of a mechanically activated composition including fly ash from the Apatity Thermal Power Plant with increased calcium content, calcite concentrate produced from apatite-carbonatite ores of the Kovdorsky deposit and natural gypsum stone. It was found that the composition, depending on the mixing ratio and curing conditions, displays characteristics of both hydraulic binder similar to lime-ash one and air binder similar to gypsum.

Samples of composite zirconium-titanium-silica sorbents were synthesized and studied by chemical, X-ray phase, BET and BJH analyses. It is shown that all the obtained samples of silica-containing Zr-Ti-SiO2 sorbents are mesoporous. In this case, the pores have a predominantly wedge-shaped shape with open ends. It was found that the modification of the obtained samples into the H+ form has less effect on their sorption capacity than their conversion to the Na+ form, does not depend on the content of SiO2 in them in the range of 10–30 % and decreases in the range of Cu2+-Cs+-Co2+-Sr2+.
