2. 建筑物的梁、板、柱、基础、地坪和道路的补强、抢修、加固（Reinforcement, emergency repair and strengthening of beams, slabs, columns, foundations, floors and roads of buildings）。
3. 可进行地脚螺栓和钢筋的锚固及结构补强（It can be used for anchoring anchor bolts and reinforcing bars as well as structural reinforcement）。
4. 地铁、隧道、地下等工程逆打法施工缝的嵌固（The embedding of construction joints in metro, tunnel, underground and other projects using the reverse construction method）。
5. 以及钢结构（钢轨、钢架、钢柱等）与基础固定连接的二次灌浆（And secondary grouting for the fixed connection between steel structures (rails, steel frames, steel columns, etc.) and the foundation）。
参考用量（Reference dosage）
参考用量计算以2.28-2.4吨/立方米的依据计算实际使用量（The reference usage is calculated based on 2.28-2.4 tons per cubic meter to determine the actual usage）。

备注（Remarks）：
1、抗压强度按：《GB177-85水泥胶砂强度试验方法》膨胀率按：《GB119-88混凝土外加剂应用技术规范》（Compressive strength is in accordance with "GB177-85 Test Method for Strength of Cement Mortar", and expansion rate is in accordance with "GB119-88 Technical Specification for Application of Concrete Admixtures".）。
2、灌浆层厚度δ≥150mm时，选用CGM-1或CGM-2灌浆层厚度30mm<δ<150mm时，选用CGM-1或CGM-2灌浆层厚度δ≤30mm时，选用CGM-1或CGM-3路面快速抢修，选用CGM-4型（When the thickness of the grouting layer δ is ≥150mm, CGM-1 or CGM-2 grouting layer is selected. When the thickness of the grouting layer δ is <δ<150mm, CGM-1 or CGM-2 grouting layer is selected. When the thickness of the grouting layer δ is ≤30mm, CGM-1 or CGM-3 grouting layer is selected. For rapid pavement repair, CGM-4 type is selected）。
施工步骤（Construction steps）：
1. 准备搅拌机具、灌浆设备、模板及养护物品，清理灌浆空间并提前将混凝土表面润湿（Prepare the mixing machinery, grouting equipment, formwork and curing items, clean the grouting space and moisten the concrete surface in advance）。
2. 支设模板并用水泥（砂）浆、塑料胶带封堵模板连接处以确保不漏水、漏浆（Set up the formwork and seal the connection points of the formwork with cement (sand) slurry and plastic tape to ensure no water or slurry leakage）。
3. 按灌浆料重量的12-15%加水量加水搅拌（Add water at a rate of 12-15% of the weight of the grouting material and stir）（机械搅拌2-3分钟，人工搅拌5分钟以上Stir mechanically for 2 to 3 minutes and manually for more than 5 minutes）
4. 将搅拌均匀的灌浆料从一个方向灌入灌浆部位。必要时可借助竹条或钢钎导流，可适当振捣或轻轻敲打模板（Pour the well-mixed grouting material into the grouting area from one direction. When necessary, bamboo strips or steel rods can be used to guide the flow. The formwork can be appropriately vibrated or gently tapped）。
5. 施工完毕后应立即覆盖塑料薄膜并加盖草帘或棉被阴湿养护3-7天（After the construction is completed, it should be immediately covered with plastic film and then covered with straw curtains or cotton quilts for damp curing for 3 to 7 days）。
6. 使用温度为-10℃至40℃。严禁在灌浆料中掺入任何外加剂或外掺料（The operating temperature range is -10℃ to 40℃. It is strictly prohibited to add any admixtures or external admixtures to the grouting material）。
