Product Description – Liquid Mortar Antifreeze with Chloride
Continuous freezing of concrete is one of the problems of concreting in cold weather conditions. Concrete will typically have lower strengths at low temperatures than concrete placed in normal weather conditions. Concrete or mortar that has been frozen even once during its early setting age will be much weaker than concrete protected from freezing. It is necessary to protect concrete or cement mortar from the possibility of freezing when it is to be applied at low temperatures. Liquid antifreeze for mortar is a liquid product, based on chloride, sodium and calcium nitrates and accelerator additives, modeled and produced and, when added to the concrete or mortar mixture, increases the speed of setting and increases the speed of the hydration process. Liquid antifreeze for cement mortar reduces the setting of concrete from 12 hours to 4 to 5 hours.
Liquid antifreeze with chloride is specially used in the construction of unreinforced concrete. Freezing of concrete before the concrete paste reaches the initial setting and acquires the expected initial strengths will cause the cement paste to expand in volume, which is caused by the freezing of water in the concrete mixture, which was supposed to participate in the hydration reaction stages before reaching the initial setting and acquiring the initial strengths, but due to the cold weather, it is frozen, so the cement in the mixture does not perform the hydration reaction and the setting is delayed. For this reason, due to the frozen water that did not participate in the hydration stages, after the ambient temperature increases and the frozen water melts, the hydration process begins, which will require re-vibration and naturally, the acquired strengths will be weak. Therefore, if the freezing of concrete occurs before setting and acquiring the necessary initial strengths, serious damage will be caused to the concrete, but whenever this freezing occurs after setting and acquiring the desired initial strength, the concrete will have more tolerance to freezing. Please note that liquid antifreeze for cement mortar is not suitable for use in reinforced concrete due to the presence of chloride in its formulation and will cause corrosion of the rebar and ultimately destruction of the concrete. Liquid antifreeze for mortar with chloride is suitable for addition to cement mortars and unreinforced concrete.
Achieving adequate strength in winter conditions is very challenging. To overcome this problem, standard antifreeze chemical admixtures are added to mortars to enhance the normal hydration process of cement. Chloride-based liquid antifreeze mortars are essential for the durability and reliability of concrete and reinforced concrete products and structures.

Consumption rate of liquid antifreeze mortar
The amount of liquid antifreeze used in mortar depends on the coldness of the ambient air during concreting and 8 to 12 hours after concreting, as well as the grade of the concrete. Therefore, predicting changes in ambient temperature should always be considered in order to accurately select the amount to be used.

How to use liquid antifreeze mortar
- The amount of liquid antifreeze in the cement mortar calculated according to the grade of concrete should be diluted with 2 times the volume of concrete mixing water. The diluted admixture should be gradually added to the concrete during mixing.
- Liquid antifreeze can be added to the ready-mixed concrete and, after complete mixing, concreting can be carried out.
- Liquid mortar antifreeze can be added to the batching or truck mixer during concrete production.
- Note that the mortar anti-liquid additive should not be poured directly onto dry cement.
Note: It is recommended to mix for at least 1 minute per cubic meter of concrete.

Mechanism of action of liquid mortar antifreeze
For concrete or mortar to set, it is essential that cement and water react to harden the concrete and achieve the required stability. The hydration stages of cement and water will be significantly slowed down at temperatures below 5 degrees Celsius. The chemical additive liquid cement antifreeze accelerates the hydration process, which is an exothermic reaction, and if the setting stages are controlled and balanced, freezing of concrete can be prevented by adding liquid cement antifreeze. Concrete antifreeze includes two other products: concrete antifreeze and mortar powder antifreeze.
Safety of liquid antifreeze mortar
- Liquid antifreeze is not classified as toxic, flammable, or environmentally hazardous.
- If your eyes get contaminated, rinse them with cold water.
- In case of contact with skin or eyes, wash with plenty of fresh water.
- If swallowed, seek medical attention immediately.
