Features of MTO ANTIFREEZE concrete antifreeze

Reinforced concrete antifreeze produced by Iran Concrete Clinic does not contain chloride and is designed based on the best introduced and standard materials for making reinforced concrete. Due to the high concentration of this concrete antifreeze, get close to the desired result without side effects with the minimum consumption of concrete antifreeze. Increasing the rate of hydration, increasing the heat generation of concrete, lowering the freezing point and accelerating the initial setting time are important features of this concrete and mortar antifreeze.

MTO ANTIFREEZE concrete antifreeze packaging

Iran Concrete Clinic's standard concrete antifreeze can be delivered in bulk or in 20 and 25 kg gallons, and up to one-ton pallets according to the customer's request.

Applications of MTO ANTIFREEZE concrete antifreeze

The use of accelerators or concrete antifreeze is generally done in concreting in cold weather conditions. Accelerators do not reduce the freezing point of water, so it is not correct to call these additives antifreeze. Accelerating additives are used to reduce the setting time and increase the obtained initial strength, especially in cold weather concreting in order to speed up the start of concrete processing and reduce the processing time. Also, increasing the speed of gaining concrete strength, especially at early ages, leads to a reduction in the time required for concrete molding and, subsequently, a reduction in overall construction costs.

Physical and chemical characteristics of MTO ANTIFREEZE concrete antifreeze

technical specifications of concrete accelerator or antifreeze additive;
Some examples of accelerators are: sodium carbonate, aluminum chloride, potassium carbonate, sodium fluoride, sodium aluminate, iron salts and calcium chloride. The old generation of quick-setting concrete additives were of alkaline type and were mostly produced with aluminate, carbonate and silicate bases. Modern accelerators include combinations of sulfate-based mineral salts that lack alkali and are available in powder and liquid physical states. The qualitative results obtained from the use of non-alkaline accelerators depend on the chemical nature of the substance, chemical compounds that make cement and other materials. Allowable concrete admixture depends. If the weather is cold and the temperature of the concrete decreases, the reaction speed of cement with water slows down and the setting time becomes longer, and as a result, not much resistance is achieved in the first hours and days. The time of mold removal will be long and during this period, damage may be done to the concrete due to vibration and impact. If frost occurs in the concrete during setting or after, when the strength of the concrete is not very high, the concrete will crack and perish due to the expansion caused by the freezing of the water in the holes, as a result of the resulting tensile stresses. The recipe tries to prevent these damages from occurring. Chemical additives, including accelerators, which are used in sprayed concrete, must follow the standards, and their technical specifications, including the amount of chloride, alkalinity, and setting time, must be examined and tested.

Considerations and technical specifications of MTO ANTIFREEZE concrete antifreeze

Concrete antifreezes are chemical substances that are added to the concrete mixing water in order to lower the freezing point of the liquid phase and are used up to -30 °C.
The use of antifreeze in concreting in cold weather has simple and very beneficial technical principles that save 20-50% of time and energy compared to steam treatment, heating concrete, etc. is.

The amount and method of using MTO ANTIFREEZE concrete antifreeze

How to use concrete antifreeze and the amount of concrete antifreeze consumption is directly related to the ambient temperature of the grade of cement used and its characteristics, and it should be noted that in calculating the ambient temperature, the minimum possible temperature should be used as the calculation criterion. Concrete antifreeze is 1% to 5% of the cement weight used. The table below can be used as a preliminary guide for the relevant tests. Please contact us to receive charts and concrete antifreeze tables.
You can add concrete antifreeze to the truck mixer before using concrete, in which case you should reduce the amount of concrete antifreeze from the water used in batching. Temperature, the amount of concrete antifreeze consumption in terms of the percentage of the weight of cement used, grade 300 grade 350 grade 400 0 to 5 - 2.5% 2% 1.5% 5 - to 10 - 3.5% 3% 2% 10 - to 15 - 5% 4% 3% The consumption of concrete antifreeze.

MTO ANTIFREEZE concrete antifreeze performance

A group lowers the freezing point of the liquid phase of concrete, as well as weak accelerators and retarders that affect the setting and hardening of cement, including electrolyte products such as: ANTIFREEZ SN and ANTIFREEZ SC. There are weak electrolyte products such as ANTIFREEZ AM and non-electrolyte products such as ANTIFREEZ U. The second category is two or three system additives. They accelerate cement hydration and also have antifreeze properties.
In addition to these two main groups, the rest have weak characteristics of antifreeze. They accelerate the setting and hardening of cement and significantly increase the amount of heat in the initial stages of cement hardening in winter concreting. These additives participate in the rapid formation of dense cement capillary structure, such as: ANTIFREEZ FS and ANTIFREEZ AS.

MTO ANTIFREEZE concrete antifreeze compounds

Concrete antifreeze ingredients are a combination of nitrogen-based inorganic and organic materials. Chloride materials have not been used in the production of this chloride-free reinforced concrete antifreeze. Nitrogen materials and calcium nitrogen in concrete antifreeze have been proposed as materials that inhibit corrosion.

MTO ANTIFREEZE concrete storage method

- The average air temperature during the day and night should be less than 5 degrees Celsius.
- The air temperature should not exceed 10 degrees Celsius for more than half a day.

The purpose of using MTO ANTIFREEZE concrete antifreeze

• Preventing damage to concrete caused by freezing in early times
• Ensuring the growth of the required strength of concrete for it
• Maintaining optimal conditions to improve strength without using additional heat during concreting
• Control of rapid temperature change in concrete to prevent cracking
• Permanent protection of the concrete structure
• You should note that hot concrete placed in a cold bed loses heat and has a temperature drop. This is very important to know if the structure has failed due to improper concrete curing and protection
• It will be useless for concrete to reach 28 days strength.

Frost-protected concrete will not fail from exposure to a single freeze cycle until it reaches a compressive strength of at least 3.45 MPa (500 psi). Concrete that is protected or possibly cured reaches its potential strength despite exposure to cold weather. Except in the heat and protection area, there is no need to provide external humidity for processing in cold weather, or this need is reduced.

Antifreeze properties of MTO ANTIFREEZE concrete

Sodium nitrate is a good and reliable antifreeze that can reduce the freezing temperature of water to minus ten degrees Celsius. But on the other hand, the final strength of concrete changes negatively by adding this compound to water. Sodium formate has a function almost similar to sodium nitrate in lowering the freezing temperature of water; with the difference that a smaller proportion of it compared to sodium nitrate can bring the freezing temperature of water to minus ten degrees Celsius.

Resistance and safety of MTO ANTIFREEZE concrete antifreeze

When using small amounts of this chemical composition, the initial compressive strength of concrete increases. This happens only if the amount of use of this substance is low; In other cases, the result will be the opposite.
