High-Strength Non-Shrink Grouting Material Product Features
1. Flowability greater than or equal to 300mm, allowing for uniform distribution and free flow after casting. 2. Good self-sealing properties with excellent fluidity; no bleeding or segregation; no need for vibration; can self-fill the grouting area due to its own weight. 3. Early high strength with high early strength: 1d strength ≥ 30MPa, 3d strength ≥ 50MPa, 28d strength ≥ 60MPa. 4. The micro-expansion grouting material utilizes composite expansion technology, featuring both pre-hardening and post-hardening expansion. It can prevent settling and water loss shrinkage of the grout, and prevent cracking and hollowing after casting, as well as reduce the effective bearing surface. 5. Durable as an inorganic blend, resistant to corrosion and aging. Domestic research shows: no significant change in strength after 2 million fatigue tests and 50 freeze-thaw cycle tests. Strength significantly improves after soaking in engine oil for 30 days. 6. Environmentally friendly, non-toxic, harmless, non-corrosive to steel reinforcement, and non-polluting to water quality and surrounding environment. 7. Suitable for winter construction, allowing outdoor work at temperatures as low as -10°C.

High-strength, non-shrink grouting material applications
(1) One-time and second-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-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 wrapped steel reinforcement for filling angle steel and column gap joints.
High-strength shrinkage-free grouting material recommended dosage
Based on the reference dosage calculation of 2.2~2.4t/m3, calculate the actual usage. It's precisely because the grouting material has high strength, far exceeding the strength achievable with cement, and alters the shrinkage characteristics of cement during curing that it is called high-strength, non-shrinkable grouting material! There are different models of grouting material, such as CGM, HGM, etc., which are determined according to the standards of different architectural research institutes. They do not represent the quality of the product. Specific usage should be tested.
High-strength, shrinkage-free grouting material application steps
1. Prepare mixers, grouting equipment, molds, and maintenance materials. Clean the grouting space and pre-wet the concrete surface. 2. Set up the molds and seal the connections with cement (sand) mortar and plastic tape to ensure no leakage or grout seepage. 3. Add water to the grouting material at 12-15% of its weight and mix (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 vibrate or tap the mold. 5. After completion, immediately cover with plastic film and add straw mats or cotton blankets for moist curing for 3-7 days. 6. Use at temperatures between -10℃ and 40℃. Strictly prohibited to add any admixtures or foreign materials to the grouting material.
Unit Consumption: Approximately 2200 kg/m³. Note: The national standard specification for grouting materials, "GB50448-2015 Application Technology Specification for Cementitious Grouting Materials," specifies compressive strength according to "GB177-85 Test Method for Compressive Strength of Cement Mortar Sand," and expansion rate according to "GB119-88 Application Technology Specification for Concrete Admixtures."
