“…At the same time, significant moisture loss is observed in concretes without maintenance: at normal hardening 22.79%, in a climatic chamber 33.66 and 44%. In the absence of care in concrete as a result of significant moisture loss, cement hydration decreases, as a result of which a decrease in strength is observed (sometimes up to 50%) [6,7].…”

The paper is devoted to the research of moisture loss from freshly laid concrete, depending on the temperature and humidity of the environment. Freshly laid concrete, hardening in a dry and hot climate, in the absence of care, under the influence of climatic conditions (high temperature, low humidity, solar radiation, dry winds). Significant moisture losses are observed, cement hydration is reduced, concrete hardening is slowed down (and may even stop), as a result, a decrease in strength is observed (sometimes up to 50%). Therefore, the study of the problems of caring for freshly laid concrete is very relevant.

The purpose of the work was to substantiate and develop technologies for the desalinization of soils by regulating the level of groundwater. The research methodology included field experiments, laboratory analyzes and mathematical calculations using formulas. The ecological and reclamation zoning of the studied massif in the Bayzak district of the Zhambyl region of Kazakhstan was carried out by the research team. A study of the hydrophysical characteristics of soils showed that 25% of the lands were non-saline, 33.3% were highly saline, and 41.7% were moderately saline soil varieties. The article presents the results of improving the efficiency of washing and watering soils using various technologies for water supply, as well as chemical reclamation elements such as phosphogypsum and manure application. It has been established that it is possible to regulate groundwater when drains are cut at a distance of 100-125 m from each other when they are located at a depth of 3 m, and the alternation of drains of different configurations using a greenhouse-type structure ensures the flow of water purified from salts through condensation into the soil. Deep loosening and the introduction of phosphogypsum and manure increased the leaching capacity of soils by 2.0-2.5 times and also accelerated the outflow of leaching fluid by 33-40%. The studied technology for the restoration of degraded soils made it possible to reduce the leaching exposure by 2.5 times compared to the traditional method. Thus, in this paper, the principles of flushing saline soils with the help of groundwater regulation were substantiated.

“…Jakhan agriculture uses 2.8 thousand km 3 of fresh water per year. This is 70% of the world's freshwater consumption, or 7 times more than the water used by global industry [1][2][3][4][5]. Almost all of this water is used to irrigate crops [6][7][8][9].…”

The paper gives recommendations on the use of mineralized collector water as an additional water resource reserve. The introduction of elements of irrigation techniques are developed taking into account the mechanical composition of the soil, the regime of seepage water and the slope of the field. The results of the research made it possible to save up to 15% of irrigation water. In the period of water shortage, the technology of using mineralized collector water with ditch water was used on cotton fields. As a result of using collector water as an additional source of water in farm fields it was possible to save river water by 50%.
