Grouting material
Product description
Ultra-high performance grouting material uses cement as the main cementing material and high-strength aggregate as the reinforcing material. Dry powder is formulated with auxiliary high-efficiency plasticizers and other substances. By adding an appropriate amount of water, it can be prepared into a slurry with good fluidity and strong self-compacting properties. The product has high early strength, slight volume expansion, no shrinkage in strength, and durability. Good performance features.
Scope of use
. Anchor bolts and bases of large equipment and precision equipment.
.Pouring for fixing steel structures (such as rails, steel frames, steel columns, etc.) to the foundation.
3. Grouting of post-tensioned prestressed steel bars.
.Beams. Columns. Structural reinforcement.
.Subway, tunnel, underground engineering construction caulking by reverse driving method.
.Thickening of wall structure and repair of water leakage.
Ultra-high performance grouting material is suitable for high chloride ion environments and the repair and construction of marine and submarine structures and floating objects, such as steel pipe sheathing and steel pipe filling. The applicable filling thickness is -. Fill thickness can be increased by adding clean, continuously graded gravel.
According to standards
Ultra-high performance grouting materials are tested according to the relevant parts of the following standards:
( ) and
B/ - "Technical Specifications for the Application of Cement-based Grouting Materials"
- "Cement-based grouting material"
Product advantages
Ultra-high durability - excellent resistance to chloride ion penetration and frost resistance, suitable for use in humid and high chloride ion content environments such as the ocean
Shrinkage compensation - the unique dual expansion system of plastic gas generation and post-hardening expansion ensures fullness in the plastic state and compensates for shrinkage in the hardened state, and the plastic gas generation system produces nitrogen to avoid corrosion of steel bars
High fluidity - excellent superplasticizer enables high fluidity and fluidity maintenance at low water-to-material ratio, ensuring the filling performance of the product
Easy construction - can be pumped or poured Use

How to use
. Base Surface:
This product must be applied without oil and without adhering loose materials. If there are any defects on the concrete surface, it must be chiseled out before construction can begin. Blow away any dust or grit from the screw holes or mounting holes. Metal surfaces must be clean and free of oil, grease or scale.
A few hours before grouting, the cleaned concrete foundation surface should be soaked in clean water. All open water must be removed before grouting.
. Mixing
Mixing should be done with a mechanically powered grout mixer for best results. If you are mixing more than kilograms of product, use a slow-speed electric drill with a high-shear blade. High-volume mixing requires a high-shear blade mixer. Mechanical mixing capacity and labor force should be sufficient to ensure continuous grouting operations. A tank with slow stirring can be used to maintain fluidity.
When mixing, first add accurately measured water into the mixer. Then add the entire package of dry mortar powder and stir for a few minutes until a smooth and uniform mortar is produced.
3. Water to material ratio: The water to material ratio is .3, and each bag of product uses 3.3 of water.
After grouting, it should be watered and cured in time, and covered with a wet straw bag or plastic film. The curing time is quite long. in 3 days.
Notes
. This product should be used in -℃ environment. The condensation time of products exceeding the above temperature may be shortened or delayed.
. This material shall not be mixed with any other cement, nor shall any admixtures be added.
3. Use this material as soon as possible after mixing it into pulp. After it loses its fluidity, it is not allowed to add water again and mix it before use.
. This product is stored in moisture-proof storage and has a shelf life of 3 months. After the shelf life, it should be tested to determine whether it can continue to be used.
. When using, refer to the construction technology method of high-strength non-shrink grouting material
Packaging, storage and transportation
The standard packaging specification is kg/bag, which should be stored in a dry and ventilated environment, waterproof and moisture-proof, unopened The shelf life is one month in this condition and can be transported as general cargo.
