PRODUCT DESCRIPTION
Russian scientists have spearheaded extensive research on antifreeze materials, especially for applications involving plain concrete, reinforced concrete, prefabricated structures, and other construction elements implemented in air or ground with temperatures colder than five °C, reaching as low as -30°C in daily minimums. Interestingly, two American scientists have also contributed necessary research to antifreeze materials in recent years.
The application of antifreeze admixtures has become a widely adopted and beneficial practice for winter concreting due to its technical simplicity and effectiveness. Compared to alternative methods like steam curing or maintaining the performance members warm, these additives offer cost savings estimated at 1.2 to 1.5 times, making it a highly economical choice. Moreover, these admixtures can be used with other methods, allowing for reduced admixture amounts, faster construction, energy savings, and additional benefits.
With over forty years of experience in Russia and extremely cold regions, concrete antifreeze admixtures have proven their efficacy for non-heatable construction environments. These admixtures serve two primary purposes: lowering the freezing point of the liquid phase of concrete and contributing to the setting and hardening process. Antifreeze materials with different properties include electrolytes like sodium nitrite or sodium chloride, weaker electrolytes like aqueous ammonia solution, and non-electrolytes of organic origin, including alcohols and urea. Some combinations, such as double or triple additive systems, can further accelerate cement hydration while providing antifreeze properties. Noteworthy examples include materials like potash, calcium chloride (CC) additives, mixtures of calcium chloride (CC) and sodium chloride (SC), nitrite-calcium nitrate + urea (CNN+u), and more.
Additionally, other antifreeze admixtures have weaker antifreeze properties, yet they accelerate the setting and hardening of the cement. For instance, iron sulfate and aluminum sulfate actively contribute to rapidly forming a dense capillary cement tube structure during concrete hardening in winter conditions.
Overall, antifreeze admixtures offer a practical and efficient solution for winter concreting, backed by decades of experience and continuous research advancements from international scientific communities.
