Concrete antifreeze, sometimes called concrete admixture or cold weather admixture, is not exactly an “antifreeze” solution, but rather an accelerator and antifreeze admixture that helps concrete work in cold weather conditions. is used Here is a summary of its functions and applications:
Standard concrete setting and curing times can be affected by cold temperatures. This can lead to possible problems such as:
Delayed increase in strength: Concrete needs more time to reach its desired strength, which affects the construction schedule and potentially delays the load bearing capacity of the structure.
Risk of Freezing: If the water in the concrete freezes before it dries properly, it can expand and damage the concrete, leading to cracks and reduced strength.

Concrete antifreeze works in two main ways:
Acceleration: These additives contain substances that accelerate the hydration process of cement in the concrete mix. This allows the concrete to set and strengthen faster even in colder temperatures.
Freezing point lowering: While not completely preventing freezing, some concrete antifreeze formulations may slightly lower the freezing point of the concrete mix. This allows more time for the hydration process before freezing disrupts the integrity of the concrete.
Cold weather construction: When pouring concrete at temperatures below the minimum recommended for standard concrete (typically around 5°C or 40°F), the use of concrete antifreeze can help ensure proper setting and curing while Help minimize the risk of frostbite injury.
Early strength requirements: Even at moderate temperatures, if a project requires the concrete to reach a certain level of strength quickly (for example, for early removal of forms or a faster construction sequence), concrete antifreeze can be used to speed up the curing process.
Antifreeze is suitable for concrete to actas an accelerator in setting and growth of resistance of early ages of concrete. Now, attention should be paid in projects where there is a possibility of corrosion at the time of operation, or concretes that are pre-treated, or in which aluminum and galvanized are used, or concretes that are in contact with water or sulfated soil, or Do not use chlorinated concrete antifreezes for concrete whose aggregates are prone to alkaline reaction. Instead,use antifreeze based on nitric acid . Caring for concrete in cold weather with concrete antifreeze :If the weather is cold, the reaction speed of cement with water slows down and the setting time during concreting is prolonged. In this case, the initial strength of concrete decreases during concreting in cold weather. The use of concrete antifreeze is required.It is necessary to protect fresh concrete from the destructive effects of freezing, concrete that has frozen even once at an early age will have less resistance to weather conditions than concrete that has not frozen , and will not be watertight.Vulnerability of concrete that is not protected against freezing is much more than concrete that is protected against freezing and also has less compressive strength. Reducing the strength, durability and quality of concrete in structures causes problems such as reducing the useful life of the building, increasing the thickness of the concrete to achieve the required cross-section, increasing the weight of the building, etc.Different solutions can be proposed to solve concrete temperature problems, but the final decision on using one or more of them depends on more detailed investigations and economic analysis of each case.One of the first and most obvious ways to increase the temperature of concrete is to heat the water used. It is also useful to protect the water source from freezing by using thermal insulation such as glass wool. One of the new ways today that uses chemistry to prevent the effects of cold weather is reinforced concrete antifreeze.

1. Concrete antifreeze is used in the production of ready concrete. 2. Concrete antifreeze is used in the production of prefabricated concrete parts .
3. Concrete antifreeze can be used to open molds quickly .
1. Concrete antifreeze improves concrete strength:Concrete antifreeze helps to increase the strength of concrete by reducing the amount of water used in the mixture. This results in stronger, more durable concrete that is less prone to cracking, shrinkage, and other damage over time. Concrete antifreeze prevents freezing of concrete.2. Concrete antifreeze reduces concrete cracking:By reducing the amount of water used in the concrete mixer mixture, concrete antifreeze helps reduce the risk of cracking. This is especially useful for concrete exposed to extreme temperatures, as it will be less prone to expansion and contraction when the temperature changes.3. Concrete antifreeze increases the efficiency of concrete:Concrete antifreeze helps make concrete more efficient and easier to spread and form. This allows you to achieve the desired results with less effort. Antifreeze of concrete makes it possible to increase the speed of initial setting. Concrete antifreeze makes it possible to pour concrete in difficult conditions.4. Concrete antifreeze reduces the cost of concreting projects:By reducing the amount of water used in the mix, concrete antifreeze helps reduce the overall cost of the concreting project. Savings in materials, labor and time can add up quickly. 
1. The minimum distance of transporting concrete is very important in the amount and consumption of concrete antifreeze .2. It is important to reduce the water consumption in concreting the foundation in cold weather .3. It is very important to use the right lubricant (preferably BS410 fast-acting superlubricant).4.

Concrete antifreeze can be a useful solution for working concrete in cold weather, but it is important to use it correctly and consider alternative methods when necessary. Consultation with an expert is recommended for guidance on the most appropriate project for your particular project and weather conditions.
