High-strength shrinkage-free grouting material product features
1. Flowability greater than or equal to 300mm, allowing for even distribution and free flow after casting. 2. Good self-sealing properties with excellent fluidity; does not leak water or segregate; no vibration required; can self-fill the casting 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 uses composite expansion technology, offering expansion before and after hardening, preventing settlement shrinkage and water loss shrinkage of the grouting material, and preventing cracking and hollowing after casting, as well as reducing the effective bearing surface. 5. Durable, inorganic mixture, 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, strength increases significantly. 6. Environmentally friendly, non-toxic, harmless, non-corrosive to steel bars, and non-polluting to water quality and the surrounding environment. 7. Suitable for winter construction, allowing for outdoor work at temperatures as low as -10°C.
Grouting material

High-strength non-shrink grouting material application
(1) One-time and second-time grouting for equipment foundations requiring high-precision installation. (2) Reinforcement embedding and anchor bolt anchoring in construction and geotechnical engineering. (3) Construction reinforcement and renovation 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 non-shrink grouting material recommended dosage
Based on a reference dosage calculation of 2.2 to 2.4 t/m³, calculate the actual usage. It's because the grouting material has a high strength, far exceeding the strength achievable with cement, and alters the shrinkage characteristics of cement during curing, that it is termed as high-strength, non-shrink grouting material. Grouting materials come in different models such as CGM, HGM, etc., which are determined according to the standards of various architectural research institutes. They do not represent the quality of the product; 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 pre-wet the concrete surface. 2. Set up the molds and seal the joints with cement (sand) slurry and plastic tape to ensure no leakage or grout escape. 3. Add water to the grouting material at 12-15% of its weight and mix (mechanically for 2-3 minutes, manually 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 molds. 5. After completion, immediately cover with plastic film and add straw mats or cotton blankets for damp curing for 3-7 days. 6. Use at temperatures between -10℃ and 40℃. Strictly prohibited to add any admixtures or external materials to the grouting material.
Unit Dosage: Approximately 2200kg/m3. Note: The national standard for grouting materials, "GB50448-2015 Technical Specification for Application of 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 Technical Specification for Application of Concrete Admixtures."
