High-Strength, Non-Shrink Grouting Material Product Features
1. Flowability exceeds or equals 300mm, allowing for uniform distribution and free flow after casting.
2. Self-sealing with good fluidity; no bleeding or segregation; no need for vibration; can fill the grouting area by its own weight.
3. Early high strength with high early strength: 1d strength ≥ 30Mpa, 3d strength ≥ 50Mpa, 28d strength ≥ 60Mpa.
4. Micro-expansion grouting material uses composite expansion technology, featuring both pre-hardening and post-hardening expansion, preventing settlement shrinkage and water loss shrinkage in the grouting material, and preventing cracking and hollowing after casting, as well as reducing the effective bearing surface.
5. Durable as an inorganic blend, resistant to corrosion and aging. Domestic research shows: after 2 million fatigue tests and 50 freeze-thaw cycle tests, there is no significant change in strength. After soaking in engine oil for 30 days, the strength is notably improved.
6. Environmentally friendly, non-toxic, harmless; no corrosion to steel reinforcement; no pollution to water quality and surrounding environment.
7. Suitable for winter construction; allows outdoor work at temperatures as low as -10°C.
Grouting material
High-strength non-shrink grouting material product applications
(1) One-time and two-time grouting for equipment foundations requiring high-precision installation.
(2) Reinforcement embedding and anchor bolt anchoring for construction and geotechnical engineering.
(3) Construction and renovation of building reinforcement projects, including beam and column joints, expansion joints, and construction joints.
(4) Emergency repair construction for roads, bridges, tunnels, airports, etc.
(5) Anchor construction for railway sleepers.
(6) Column wet encased steel reinforcement for filling angle steel and column gap joints.
High-strength shrinkage-free grouting material recommended dosage
The reference dosage calculation is based on 2.2 to 2.4 t/m3, and the actual usage is determined accordingly. It is called high-strength, non-shrink grouting material precisely because of its high strength, which far exceeds the strength achievable with cement, and it alters the shrinkage characteristics of cement during curing. There are different types of grouting materials, such as CGM, HGM, etc., which are determined according to different standards set by building research institutes. This does not represent the quality of the product, and specific usage should be tested.
High-strength, non-shrink grouting material application steps
1. Prepare mixers, grouting equipment, molds, and curing materials, clean the grouting space, and moisten the concrete surface in advance.
2. Set up molds and seal the joints with cement (sand) mortar and plastic tape to prevent leakage of water or grout.
3. Add water to the grouting material at a rate of 12-15% of its weight and mix it (mechanical mixing for 2-3 minutes, manual mixing for over 5 minutes).
4. Pour the well-mixed grouting material into the grouting area from one direction. Use bamboo sticks or steel rods for guidance if necessary, and gently tap the mold for compaction.
5. After construction, cover with plastic film immediately and cover with straw mats or cotton blankets for damp curing for 3-7 days.
6. Use between -10℃ and 40℃. Strictly prohibited to add any admixture or external material to the grouting material.
Unit Dosage: Approximately 2200 kg/m³
Note: The national standard specification for grouting materials, "GB50448-2008 Application Technology Specification for Cementitious Grouting Materials," specifies the compressive strength according to "GB177-85 Test Method for Compressive Strength of Cement Mortar Sand," and the expansion rate according to "GB119-88 Application Specification for Concrete Admixtures."
