High-Strength Non-Shrink Grouting Material Product Features
1. Flowability exceeds or equals 300mm, allowing for uniform spreading and free flow after casting. 2. Good self-sealing properties with excellent fluidity; no water leakage or segregation; no vibration required; fills the grouting area by its own weight. 3. Early high strength with high early strength: 1-day strength ≥ 30Mpa, 3-day strength ≥ 50Mpa, 28-day strength ≥ 60Mpa. 4. Micro-expansion grouting material uses composite expansion technology, with expansion before and after hardening, preventing settling shrinkage and water loss shrinkage in 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, strength shows no significant change. After soaking in engine oil for 30 days, strength significantly improves. 6. Environmentally friendly, harmless, non-corrosive to steel reinforcement, and non-polluting to water quality and the surrounding environment. 7. Suitable for winter construction; outdoor work can be carried out at temperatures as low as -10℃.
Grouting material
High-strength non-shrink grouting material product applications
(1) One-time and second-time grouting for equipment foundations requiring high-precision installation. (2) Reinforcement embedding and anchor bolt fixation for construction and geotechnical engineering. (3) Grouting for structural 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 bolt construction for railway sleepers. (6) Column wet steel jacket 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 is precisely 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 high-strength, non-shrink grouting material. Grouting materials come in different models, such as CGM, HGM, etc., which are determined according to standards set by various architectural research institutes. They do not represent the quality of the product. Specific usage should be determined through testing.

Steps for High-Strength Non-Shrink Grouting Material Application
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 joints with cement (sand) mortar and plastic tape to ensure no leakage or grout seepage. 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 vibrate or tap the mold. 5. After construction, 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 from adding any admixtures or external materials to the grouting material.
Unit Consumption: Approximately 2200 kg/m³ Note: The national standard specification for grouting materials, "GB50448-2015 Application Technical Specification for Cement-based 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 Technical Specification for Application of Concrete Admixtures."
