How to use Sihai Huinong antifreeze?
The usage method is as follows: For construction at 0~ -5℃, 4~6% can be added. For construction at -5~ -10℃, 5~8% can be added at -10~ -15℃ Under construction conditions, 8~10% concrete antifreeze can be added. Early strength antifreeze 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. The effect is remarkable.
What is the ratio of early-strength antifreeze?
1. Concrete early strength agent ratio
1. Dosage: generally 3-6% of cement.
2. In order to maintain the uniform quality of the concrete mixed with this agent, the mixing time should be extended by 1-2 minutes.
3. Concrete (tong) mixed with this agent cannot be used in orthopedics with active minerals (such as opal).
4. If this agent is damp and agglomerated, it must be crushed or weathered before use. Its performance will remain unchanged.
2. Concept of retarded concrete
Concrete early strength agent is one of the concrete admixtures, which refers to admixtures that can increase the early strength of concrete and have 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
The characteristics of early strength antifreeze What is the applicable temperature?
Hebei Zhusheng Building Materials Technology Development Co., Ltd. produces ZS-102 early-strength antifreeze, which has anti-freezing, lowering freezing point, and significant early-strength effects during use. It can shorten the natural curing time of concrete and improve Frost resistance and impermeability of concrete.
It is an antifreeze composed of components such as water reduction, early strength, freezing point reduction, and frost damage prevention. It has multiple functions such as early strength, antifreeze, appropriate air entrainment, and corrosion protection.
Significantly improves the early strength, and the strength continues to increase in the middle and late stages. It is an ideal admixture product for winter construction.
Early-strength antifreeze is suitable for mortar and concrete projects within the range of -15℃.
How to use cement antifreeze correctly in winter?
According to the specification, the usage method is as follows:
When constructing at 0~-5℃, 4~6% can be added. When constructing at -5~-10℃, 4~6% can be added. When constructing at 5~8% -10~ -15℃, 8~10% concrete antifreeze can be added. Early strength antifreeze uses special antifreeze materials, which can effectively reduce the freezing point of concrete and mortar, and greatly improve the performance of concrete and mortar at negative temperatures. Lower frost resistance.
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. The effect is remarkable.
When to add early strength antifreeze?
The dosage of Gallux early-strength antifreeze is 3%~5% for cement. When the temperature is about -5 degrees, the optimal dosage is 4%; when the temperature is about -10 degrees When the temperature is -15 degrees, the optimal dosage is 5%; when the temperature is -15 degrees, it is appropriate to mix 4% to 6%. Can be added directly to the blender for use. The mixing time should be appropriately extended by 1 to 2 minutes.
This agent has a water-reducing effect. The actual amount of water added can be determined through trial mixing according to the required mortar consistency requirements.
The ambient temperature should be kept above -5 degrees when plastering
