Product Description
The prestressed pipe grouting material has passed the international quality management system certification and is supervised by the Highway Science Research Institute of the Ministry of Transport. It is mainly composed of cement, special admixtures, supplemented by a variety of mineral modified components and high-quality Made up of molecular polymer materials. It has the characteristics of low water-to-binder ratio, high fluidity, zero bleeding, micro-expansion, and good durability. During construction, it is directly added with water and stirred. The performance of the product has reached the international leading level after being identified by the Science and Technology Department of the Ministry of Transport.
Product Usage
It is widely used for grouting of various beam prestressed pipes and grouting of equipment foundations, anchors and other components. It can also be used for nuclear power plant shell grouting, loose concrete, cracks and holes and other defect repairs. .

Construction instructions
First add Appropriate amount of water cleans the equipment and also moistens the barrel wall. Then add water to the scale line position of the pulping machine, turn on the mixing pump and circulation pump, and add (package) the grouting material at a constant speed. The pulping machine should be in working condition during the feeding process. After the feeding is completed, stir ~, and introduce the slurry into the storage tank and stir until Grouting completed.
Packaging and Storage
Net weight of each bag, packed in paper-plastic composite bags
Avoid damaging the packaging bags during transportation and storage, and strictly prevent moisture and direct sunlight
Shelf life is months.
1. Product Features
Early strength and high strength, high hourly strength, and the strength can reach above in one day. Production can be started the day after the equipment is installed.
The self-leveling site only needs to add water and stir, and then pour it directly into the equipment foundation. It can fill all the gaps in the equipment foundation without vibrating. Liquidity is available.
Emblem expansion ensures close contact between the equipment and the foundation.
The strength of anti-oil penetration after being immersed in engine oil is higher than before being immersed in oil.
The durability has been tested for 10,000 times of fatigue tests, and the strength has not changed significantly in the freeze-thaw cycle test.
2. Scope of application
Injection of anchor bolts of large equipment and precision equipment, secondary injection of machine base.
, secondary pouring for the fixed connection between steel structure and concrete.
, post-tensioned prestressed reinforced concrete channel pouring under low negative temperature.
