How much antifreeze should be added to one side of concrete? Huaibei early strength antifreeze price, Suzhou antifreeze manufacturer, Xuzhou genuine antifreeze

During concrete construction, in order to prevent cold air from affecting the performance of the concrete, an appropriate amount of concrete will be added. But how much antifreeze should be added to the concrete? Let’s take a brief look at it.

1. How much antifreeze should be added to the concrete

Add 2% of the cementitious material to 5%. Depending on the strength level of the concrete and the temperature of the construction environment, the proportion of antifreeze that needs to be added is also different. The actual situation shall prevail. Because concrete contains a certain proportion of water, if it is exposed to subzero cold air, a freezing reaction will occur, which will affect the solidification of the concrete. Therefore, antifreeze needs to be added to improve the strength of the concrete in the early stages of solidification. However, because concrete has high requirements for the mix ratio, antifreeze The addition ratio cannot exceed 5% to avoid affecting the strength.

2. What should be paid attention to in concrete construction

1. Because concrete has several strengths, Depending on the strength, the selected cement powder materials are different, and the mix ratio is also different. Therefore, during construction, the operation must be strictly based on the site conditions and the strength of the concrete. Otherwise, the workability of the concrete will be affected, resulting in the complete curing of the concrete in 28 days. Finally, the strength was not up to standard.

2. The main materials of concrete are cement powder and water. When the cement powder is mixed with water, a curing reaction will begin. If the concrete has solidified, it will It will affect the final strength, so when mixing concrete, you need to control the amount according to the construction speed, and it must be used within 5 hours.

3. Concrete is relatively viscous. During construction, a vibrator must be used to ensure uniform internal vibration and avoid the appearance of cracks inside the concrete. Bubbles, otherwise it will directly affect the strength of concrete.

Editor’s summary: The above is about how much antifreeze should be added to concrete and what should be paid attention to in concrete construction. I hope it will be helpful to you. When constructing concrete, the mixing ratio must be strictly controlled, otherwise it will affect the workability of the concrete and the final solidification effect.
