How much antifreeze is added to one ton of cement?
One ton of cement plus about 35 kilograms of antifreeze. The amount of antifreeze added is usually 3.5% of the cement dosage, with a maximum of no more than 5%. Generally, the amount of antifreeze added is 5% of the concrete volume, which is closely related to the concrete strength and concrete volume.
Adding antifreeze to concrete can ensure normal use of concrete at low temperatures. Of course, if water-reducing agent and air-entraining agent are added at the same time, the antifreeze effect will be better.
How much antifreeze can be added to a bag of cement?
5%.
In winter, in order to ensure the quality of cement, everyone will add antifreeze to the cement. The amount of antifreeze is not always better, but depends on the total amount of cement. If it exceeds this value , will affect the quality of cement. When buying cement in winter, you can ask the manufacturer to help you prepare the amount of antifreeze. The amount you prepare yourself will definitely not be accurate enough.
How many bags of cement can one kilogram of antifreeze last?
Generally, 3% to 5% of cement is mixed.
One bag is calculated as 100kg, which means adding about 3kg-5kg.
The antifreeze agent uses special antifreeze materials, which can effectively reduce the freezing point of concrete and mortar, and greatly improve the antifreeze performance of concrete and mortar at negative temperatures.
And it can increase the early strength of concrete and mortar by more than 80% without reducing the later strength, thereby ensuring that the strength is equally developed under positive and negative temperature conditions, and the effect is significant. One ton of cement uses 30-50 kilograms of antifreeze.

What is the mix ratio of mortar antifreeze?
Cement mortar antifreeze is combined with winter temperature conditions, which can accelerate the condensation and hardening of concrete under negative temperature conditions. The strength increases significantly and does not affect the development of later strength. It is chloride-free to avoid steel bar corrosion and improve The durability of concrete.
Dosage: The specific dosage can only be determined after a concrete mix test. General dosage ratio (by weight):
Liquid: temperature -5 ~ -20℃, accounting for 2.0-5.0% of the cementitious material
Powder: temperature -5 ~ -20 ℃ accounts for 2.0-5.0% of cementitious materials
Function: Mainly used in commercial concrete, suitable for reinforced concrete, prestressed concrete and fly ash-mixed concrete
At what temperature can antifreeze cement be constructed?
There is no limit to the external temperature in cement construction, but when the average temperature is lower than 5℃ for five consecutive days, winter construction measures should be taken. In other words, low temperature has an impact on the quality of concrete, but as long as there are corresponding guarantee measures, such as shed maintenance, thermal storage method construction, etc., it can be constructed.
On expressways and first-class highways, it can be made into a trapezoidal section that gradually thickens from the inside to the outside edge. Most pavement panels are made into a single-layer type; when the board is thicker, it can also be made into a double-layer type, with the thickness of the upper layer not less than 6 to 7 cm. The lower layer is made of low-strength concrete using materials of lower quality; in order to make the upper and lower layers firmly bonded, the surface of the lower layer should be clean, rough and grooved.
How much early-strength antifreeze should be added per m3 of concrete?
3-6% early strength antifreeze of cement should be added to every m3 of concrete. Introduction: Concrete antifreeze early strength admixture refers to an admixture that can improve the early strength of concrete and has no significant impact on the later strength. The main function of early strength agent is to accelerate the hydration rate of cement and promote the development of early strength of concrete; it has both early strength function and certain water reduction and enhancement function. Concrete early strength agent is one of the earliest types of admixtures used in the history of admixture development. So far, people have developed a variety of early-strength additives other than chloride and sulfate, such as nitrite, chromate, etc., as well as organic early-strength additives, such as triethanolamine, calcium formate, urea, etc. On the basis of early-strength additives, a variety of composite admixtures are produced and applied, such as early-strength water-reducing admixtures, early-strength antifreeze and early-strength pumping agents. These types of early-strength admixtures have been used in actual projects and have played an important role in improving concrete properties, increasing construction efficiency and saving investment costs. </p
