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". The expansion rate is in accordance with: "GB119-88 Technical Code 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型；路面快速抢修，选用CGM-4型（When the thickness δ of the grouting layer is ≥150mm, CGM-1 or CGM-2 should be selected. When the thickness of the grouting layer is 30mm<δ<150mm, CGM-1 or CGM-2 should be selected. When the thickness δ of the grouting layer is ≤30mm, CGM-1 or CGM-3 types should be selected. For rapid road surface repair, the CGM-4 type is selected）。

拆模和养护时间及环境温度的关系（The relationship between formwork removal and curing time and environmental temperature）

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. 将灌浆料重量的12-15％加水量加水搅拌（机械搅拌2-3分钟，人工搅拌5分钟以上）（Add 12-15% of the weight of the grouting material with water and stir (mechanically stir for 2-3 minutes, manually stir 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. 施工完毕后应立即喷洒养护剂或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, a curing agent should be sprayed immediately or the area should be covered with plastic film and then covered with straw MATS 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 from -10℃ to 40℃. It is strictly prohibited to add any admixtures or external admixtures to the grouting material.）。

包装贮运Packaging, storage and transportation

1. 灌浆料为50kg袋装，存放在通风干燥处并防止阳光直射（The grouting material is packed in 50kg bags and should be stored in a well-ventilated and dry place, protected from direct sunlight.）。

2. 保质期为3个月，超出保质期应复检合格后方可使用（The shelf life is 3 months. If it exceeds the shelf life, it should be re-inspected and found qualified before use.） 。
