Winter concreting under negative temperatures is associated with significant technological and economic challenges, primarily due to the need to prevent early freezing and ensure the required strength development of concrete. Traditional methods, such as electrical heating, lead to increased energy consumption and labor costs. This study investigates the effectiveness and economic efficiency of using a complex anti-freezing chemical admixture “Beton-Strong 17” in monolithic concrete structures under cold weather conditions.

Experimental studies were carried out using Portland cement II/A 32.5N with the incorporation of the chemical admixture under negative temperature conditions. The performance of concrete produced with the admixture was compared with conventional electrically heated concrete in terms of strength development, material consumption, and total production cost. Real construction projects were used to validate the obtained results.

The results show that the use of the anti-freezing admixture allows a reduction in cement consumption by up to 30% while maintaining the required concrete strength class (B30). Economic analysis demonstrated that the total cost of 1 m³ of concrete was reduced by approximately 92,400 UZS compared to the electrical heating method.
