As we all know, there are many types of concrete admixtures. Different types have different characteristics and their uses are naturally different. Among them, concrete water-reducing agents and antifreeze agents are the two main categories. Many people don’t know how to use it correctly. I don’t even know if concrete water reducing agent and antifreeze can be used at the same time. Today I will help you solve this problem.
Generally speaking, concrete water-reducing agent and antifreeze can be used at the same time. The dosage should be determined according to the specific construction site. The same is true for early-strength antifreeze. It can be used together with water-reducing agent, but early-strength antifreeze itself has the function of reducing water. Therefore, there is no need to add water reducing agent to meet the splash water requirements.
In addition, when configuring and using early-strength agent, early-strength water-reducing agent and antifreeze, the following matters need to be paid attention to:
1. It is necessary to ensure full dissolution, and the upper and lower concentrations of the solution must be uniform. In order to accelerate dissolution, use hot water of 40-70 degrees Celsius.
2. The temperature of sodium sulfate should not be greater than 20%. It should be stored at a positive temperature and the concentration of the device should be measured before use. If crystals or precipitation are found at the bottom of the container When using, attention should be paid to hot stirring until it is completely dissolved before use.
3. When the admixture is suitable for use, attention should be paid to its co-solubility. For example: calcium chloride, calcium nitrate and calcium nitrite solutions cannot be mixed with sodium sulfate solution.
