KC-FZ Early Strength Agent
KC-FZ agent is a non-chlorine salt powder multi-functional admixture, which has the functions of early strong plasticization, water reduction and comprehensive modification. The product compound GB8076-2008 standard
Product Description
Main technical performance
1. This product is gray solid powder.
2. Shorten the curing time, and the natural curing concrete can reach the design label or the curing time of 70% of the design mark, which can be shortened by 1/2—3/4.
3. can improve the strength of concrete, and save 10-20% of cement.
4. When the same slump is maintained, water can be reduced by 12%. The slump of non-reducing concrete can be increased by about two times to improve construction operating conditions.
5. Significantly improve the impermeability and resistance of concrete and the ability of freezing cycle.
6. Reduce the carbonization speed, improve the durability of reinforced concrete, and have certain rust resistance to the steel in the concrete.
7. Can prevent construction under negative temperature from early freezing damage. When the normal temperature is restored, its strength still develops normally, and other properties are not damaged.
Scope of application
The early strength agent is suitable for ordinary Portland cement, slag Portland cement, volcanic ash Portland cement concrete, and can also be used for prestressed concrete structures.
Usage and precautions
1. The dosage of early strength agent is: 3-4% of the weight of the cement.
2. Dry powder does not need to prepare a solution, the product can be directly added to the concrete according to the regulations, the mixing time is extended by 50% than normal.
3. The concrete has good thixotropic properties, which can appropriately reduce the slump and affect the workability of concrete.
4. The early strength agent should be strengthened to maintain, especially in the higher temperature season construction should pay attention.
5. When the initial early strength agent is added, the concrete preparation experiment should be carried out according to the quality of the local raw materials and the construction conditions to guide the construction.
Packaging and storage
1. This product is 50KG double-layer plastic film packaging.
2. This product is stored in a cool and dry warehouse to avoid moisture.
3. The shelf life is two years, and the overdue period can still be used after passing the test.
