THE ROLE OF CHEMICAL ADDITIVES IN INCREASING THE STRENGTH OF CONCRETE IN THE CONSTRUCTION OF OIL AND GAS FACILITIES

Abstract

The aim of the article is to study the role of chemical additives in increasing the strength of concrete in the construction of oil and gas facilities. It is noted that various chemical additives improve the mechanical properties of concrete and ensure long-term operation in harsh environmental conditions. It is emphasized that water reducers (plasticizers and superplasticizers) increase the density of concrete by reducing the water-cement ratio, resulting in concrete with high compressive strength. It is also noted that corrosion inhibitors protect steel reinforcement in concrete, preventing rust and destruction.
The research used analysis, synthesis and comparative methods. Systematic, process, resource and effective approaches were used to achieve the scientific results of the work.
The scientific novelty of this research is that it comprehensively addresses the effects of chemical admixtures that increase the strength of concrete used in the construction of oil and gas facilities, revealing how concrete technology adapts to the specific requirements in this field. The effects of various chemical admixtures on the mechanical properties and environmental durability of concrete fill the gaps in the literature in this field and provide a new perspective to optimize the sustainable performance of concrete. In particular, the in-depth analysis on the selection and use of concrete admixtures for the unique operating conditions of oil and gas facilities constitutes a significant innovation compared to previous studies in this field.
As a result, chemical additives used to increase the strength of concrete in the construction of oil and gas facilities play a critical role in ensuring structural integrity and building long-lasting, safe facilities. These additives significantly improve both the mechanical properties of concrete and its resistance to environmental factors. Water reducers reduce the water-cement ratio, resulting in denser and more durable concrete, while accelerators and retarders control the setting process of concrete, providing time efficiency in construction processes.
