“…In the course of the research, a gypsum binder was used, obtained on the basis of synthetic gypsum derived from the coagulation sediment of natural waters and sulfuric acid waste (Romanovski et al, 2023;Panchenko and Kharchenko, 2020). Synthetic gypsum obtained on the basis of iron-containing sediments of the natural water coagulation station being powder product with a moisture content in the range of 9-15 wt.%, was obtained by the decomposition reaction of CaCO 3 with sulfuric acid.…”

“…Based on the problem of water resistance of gypsum binders, the task was to improve this property. A review of the literature data led to the conclusion that an increase in water resistance is possible not only with the introduction of additives of mineral origin, but also on the basis of technogenic products (Chernysheva et al, 2018;Romanovski et al, 2023;Panchenko and Kharchenko, 2020;Combe and Smith, 1968). The objectives of this study were: i) increasing the water resistance of a gypsum binder obtained on the basis of sulfuric acid waste and coagulation sediment of natural waters by introducing additives; ii) the use as additives of water-resistance-improving wastes from various industries and the establishment of the optimal amount at which water resistance is increased and as well as stage in which no signi cant deterioration in the basic properties of the gypsum binder is observed.…”

The article presents the possibility of increasing the water resistance of gypsum binders (GBs) obtained based on synthetic gypsum by introducing additives derived from industrial wastes. Regularities were obtained for the influence of the type and amount of additives on the water/gypsum ratio (W/G), strength indicators and water resistance of high-strength GB. The introduction of a single-component additive to improve water resistance does not have a significant effect. Complex additives based on Portland cement, granulated blast-furnace slag, electric steel-smelting slag, expanded clay dust and granite screenings of various fractions have been developed that make the maximum contribution to improving the water resistance of a high-strength GB based on synthetic calcium sulphate dihydrate, which made it possible to increase the water-resistance coefficient from 0.39 to 0.82.

“…The applications of nanotechnology, or the use of nanomaterials in agriculture, can be handy to address the challenges associated with the creation of effective and potentially effective approaches for the control of insect pests in agriculture. Different types of NPs (Figure 1) have been transformed into nanopesticides and nanofertilizers, including carbon nanotubes, silicon, molybdenum, silver, copper [27,28], zinc [29,30], manganese [31], titanium [32,33], iron and its oxides [34], and nanoformulations of common agricultural inputs including phosphate, urea, sulphur, validamycin, tebuconazole, and azadiractin [35]. Recent developments in chemistry and material science have helped us master nanoparticle technology, which has significant implications for agriculture [36].…”

Nanotechnology has an extensive series of applications in agronomy and has an important role in the future of sustainable agriculture. The agricultural industries should be supported by innovative active materials such as nanofertilizers, nanofungicides, and nanopesticides. It is necessary in the current situation to meet the dietary needs of the constantly expanding world population. Nearly one-third of crops grown conventionally suffer damage, mostly as a result of pest infestation, microbiological assaults, natural disasters, poor soil quality, and a lack of nutrients. To solve these problems, we urgently need more inventive technology. The application of nanotechnology in agriculture provides intelligent methods for delivering nutrients, herbicides, and genetic materials for improving soil fertility, stress tolerance, and protection. The world is currently confronting significant issues related to the rising demand for enough food and safe food as well as dealing with the environmental damage caused by traditional agriculture. Nanomaterials have important applications in agriculture for increasing plant growth and development and the quality and quantity of the crops and controlling and managing agricultural diseases. The major objective of this article is to describe the various applications and importance of nanoparticles in the agriculture sector.

A method has been developed for separating a mixture of calcium, magnesium and sodium sulfates obtained through the interaction of sulfuric acid and waste from the water purification process generated by using membrane filters. The primary goal of this method is to extract gypsum and produce gypsum‐based binders. Patterns were identified regarding how various types, ratio and quantities of additives: blast furnace slag, granite screenings, portland cement, electric steel smelting slag affect the water‐gypsum ratio, strength properties, and water resistance of high‐strength gypsum binders. It was found that adding a single‐component additive specifically to enhance water resistance does not significantly impact these properties. Complex additives have been developed based on Portland cement, granulated blast furnace slag, electric furnace slag, expanded clay dust, and granite screenings of various fractions. These additives are designed to maximize the water resistance of high‐strength gypsum binder based on synthetic calcium sulfate dihydrate. As a result, the water resistance coefficient increased from 0.45 to 0.52. Additionally, a technological block diagram of the process has been proposed.
