I. Product Introduction
Our Concrete antifreeze pumping agent is a composite admixture composed of a variety of organic and inorganic materials with different functions. It has the characteristics of anti-freeze damage, early strength, enhancement, water reduction, strong plasticization, and reduction of slump loss. Our Concrete antifreeze pumping agent does not contain chlorine salt and has no corrosion effect on steel bars.
II.Technical performances
1. Water reduction rate: The water reduction rate of this product> 15%.
2. Concrete antifreeze pumping agent can greatly improve the fluidity of concrete, has good plasticity retention, small slump loss, can improve the workability of concrete, does not produce bleeding segregation, and is conducive to pumping.
3. It can improve the early strength of concrete, prevent the concrete from suffering early freezing damage, and accelerate the development of strength.
4. This product has good adaptability to various cements and is widely used.
1. Suitable for concrete construction under the natural temperature of 0℃-15℃.
2. It is suitable for concrete requiring normal construction under alternating positive and negative natural temperature and in winter, such as industrial, civil buildings, roads, bridges, and ports.

III. Applicable methods
1.The dosage is 3%-5% of the weight of the cementitious material.
2. When adding Concrete antifreeze pumping agent, it should be accurately measured, and it is strictly forbidden to miss and repeat the addition.
3. Before construction, the optimal mixing amount should be determined by trial configuration according to the requirements of the project.
4. After the concrete is formed, the maintenance work should be done well, and the insulation material should be used to cover it, and no watering should be allowed for maintenance under negative temperature conditions.
IV. Packaging, Transportation and Storage
Our Concrete antifreeze pumping agent is liquid, packed in plastic barrels, 1 ton per barrel, and can also be transported by tanker. The storage process should prevent leakage, exposure and high temperature.
