Grouting material is composed of high-strength aggregates, cement as the binder, and supplemented with substances such as high fluidity, slight expansion, and anti-segregation. It is ready for use after adding a certain amount of water on the construction site and being mixed thoroughly.

The purpose of grouting material:

1. Suitable for reinforced and reinforced concrete beam-column interfaces.

2. Suitable for equipment foundation grouting for machine bases, anchor bolts, etc.

3. Reinforcement, repair, and strengthening of building beams, slabs, columns, foundations, ground levels, and roads.

4. Bonding of construction joints for subway, tunnel, underground, and similar projects.

5. And secondary grouting for the connection of steel structures (rails, frames, columns, etc.) to foundations.

Zhuhai Non-Shrink Grouting Material Grouting Instructions

I. Basic Processing

The base surface should be roughened. Clean the base surface, ensuring there are no debris such as gravel, slurry, dust, oil stains, and release agents. The base surface should be thoroughly moistened 24 hours before grouting and cleared of standing water 1 hour before grouting. 1. Set up forms according to the grouting construction drawing. Seal the joints between the formwork and the base, and between formwork panels, with cement slurry and tape to prevent any water leakage from the overall formwork. 2. The horizontal distance between the formwork and the bottom of the equipment should be controlled at about 100mm to facilitate grouting. 3. The top elevation of the formwork should be 50mm higher than the surface of the equipment base. 4. In case of leakage during grouting, it should be addressed promptly. Zhuhai Non-shrink Grouting Material 3. Grouting Material Preparation 1. Generally, add water according to the standard of 13-14% for general reinforcement type, and 9-10% for pebble reinforcement type. 2. The mixing of high-strength non-shrink grouting material can be done manually or mechanically. It is recommended to use a mixer for mechanical mixing to ensure thorough and even mixing, with a mixing time of 3-5 minutes. Manual mixing should be completed within 5 minutes. The mixed grouting material should be used within 40 minutes as its fluidity decreases with increased storage time. It is strictly prohibited to add any admixtures to the high-strength non-shrink grouting material. Zhuhai Non-shrink Grouting Material 4. Grouting Construction 1. For longer equipment or track foundations, segmented construction should be adopted. 2. Once grouting begins, it must be continuous without interruption, and the grouting time should be minimized as much as possible. Zhuhai Non-shrink Grouting Material 5. Curing 1. After grouting, immediately cover the grouting material with straw bags or mineral wool blankets after the initial setting, and maintain moisture. 2. During winter construction, the grouting material, mixing water, and curing measures should comply with the relevant provisions of the current "Code for Construction Quality Acceptance of Concrete Structure Engineering" (GB50204). 3. The grouted material should not be subjected to vibration for 24-36 hours after grouting to avoid damaging the unhardened grouting layer.

ZhuHai Non-Shrink Grouting Material Grouting Instructions

I. Basic Processing

The base surface should be roughened. Clean the base surface, ensuring no debris such as碎石, floaty slurry, floating dust, oil stains, and release agents are present. The base surface should be sufficiently moistened 24 hours before grouting, and standing water should be cleared 1 hour before grouting. Two, Formwork: 1. Set up the formwork according to the grouting construction drawing. Seal the joints between the formwork and the base, and between formwork panels, with cement slurry and tape to achieve a watertight formwork. 2. The horizontal distance between the formwork and the bottom of the equipment should be controlled at about 100mm to facilitate grouting. 3. The top elevation of the formwork should be 50mm higher than the surface of the equipment base. 4. If any leakage occurs during grouting, it should be addressed promptly. Zhuhai Non-shrink Grouting Material Three, Grouting Material Preparation: 1. Generally, add water to mix according to the standard of 13-14% for general reinforcement type, and 9-10% for pebble reinforcement type. 2. The mixing of high-strength non-shrink grouting material can be done mechanically or manually. It is recommended to use a strong mixer for mechanical mixing to ensure thorough and even mixing, with a mixing time of 3-5 minutes. Manual mixing should be completed within 5 minutes. The mixed grouting material should be used up within 40 minutes as the setting time increases. It is strictly prohibited to add any admixtures to the high-strength non-shrink grouting material. Zhuhai Non-shrink Grouting Material Four, Grouting Construction: 1. For longer equipment or track foundations, segmented construction should be used. 2. Once grouting begins, it must be continuous and uninterrupted, and efforts should be made to minimize the grouting time. Zhuhai Non-shrink Grouting Material Five, Curing: 1. After grouting is completed and the grouting material starts to set, immediately cover it with straw bags or mineral wool blankets and maintain moisture. 2. During winter construction, the grouting material, mixed water, and curing measures should comply with the relevant provisions of the current "Code for Acceptance of Construction Quality of Concrete Structures" (GB50204). 3. The grouting material should not be subjected to vibration for 24-36 hours after grouting to avoid damaging the unhardened grouting layer.
