High-Strength Non-Shrink Grouting Material Product Features
1. Flowability is greater than or equal to 300mm, allowing for even dispersion and free flow after casting. 2. Self-sealing with good fluidity; does not leak or segregate; no vibration required; can fill 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. The micro-expansion grouting material uses composite expansion technology, offering both pre-hardening and post-hardening expansion, preventing settling 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 mixture, resistant to corrosion and aging. Domestic studies show: no significant change in strength after 2 million fatigue tests and 50 freeze-thaw cycle tests. Strength increases significantly after soaking in engine oil for 30 days. 6. Environmentally friendly, harmless, non-corrosive to steel reinforcement, and non-polluting to water quality and the surrounding environment. 7. Suitable for winter construction, allowing outdoor work at temperatures as low as -10°C.
Grouting material
High-strength, non-shrink grouting material application
(1) One-time and two-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 iron and column gap joints.
High-strength non-shrink grout recommended dosage
Based on a reference dosage calculation of 2.2 to 2.4 t/m3, calculate the actual usage. It's 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 as high-strength, non-shrink grouting material!! There are different types of grouting materials, such as CGM, HGM, etc., which are determined according to standards set by various architectural 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 maintenance items. Clean the grouting area and moisten the concrete surface in advance. 2. Set up 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 a rate of 12-15% of its weight and mix (mechanical mixing for 2-3 minutes, hand mixing for more than 5 minutes). 4. Pour the well-mixed grouting material into the grouting area from one direction. If necessary, use bamboo sticks or steel rods to guide the flow and gently tap the molds. 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 within a temperature range of -10℃ to 40℃. Strictly prohibit 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 Technology 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 Application Technology Specification for Concrete Admixtures."
