CGM High-Strength Non-Shrink Grouting Material

Grout material is made by using high-strength materials as aggregates, cement as the binder, and supplemented with substances such as high fluidity, slight expansion, and anti-segregation.   It adds a certain amount of water on the construction site, stirs it well, and it's ready to use. It offers advantages such as cost reduction, shortened construction time, and ease of use.

Usage Instructions  
1. Basic Processing
Clean the base surface of the sweeping equipment, ensuring there are no debris such as gravel, slurry, dust, oil stains, and release agents. Before grouting,24 hours, the base surface of the equipment should be fully moistened. One hour before grouting, standing water should be cleared.
2. Determine Grouting Method
Based on the actual conditions of the equipment base, select the corresponding grouting method. Due to the excellent flow properties of the grouting material, in most cases, using"Gravity Grouting" is sufficient, where the slurry is directly poured into the mold opening, relying entirely on its own weight to level out and fill the entire grouting space. In cases where the grouting area is large, the structure is particularly complex, or the space is small with a significant distance, "High-Position Funnel Grouting" or "Pressure Grouting" can be used to ensure the slurry fills all corners adequately.
3. Formwork
Based on the determined grouting method and the grouting construction drawing for setting up forms, the elevation of the form should be at least 10 inches higher than the surface of the equipment base.50mm, the template must be securely and firmly set up to prevent loosening and leakage of concrete.

4. Grouting Material Mixing
Determine the water amount based on the recommended water material ratio on the product's certificate. The water for mixing should be potable, with the water temperature kept atOptimal temperature range is 5-40°C, mechanical or manual stirring is acceptable. For mechanical stirring, the general stirring time is 1-2 minutes. For manual stirring, first add 2/3 of the water and stir for 2 minutes, then add the remaining water and continue stirring until uniform.
5. Grouting
Grouting construction should comply with the following requirements:   
1，The slurry should be poured from one side until it overflows from the other, to facilitate the expulsion of air between the equipment base and the concrete foundation, ensuring the grout is fully compacted. Grouting should not be conducted simultaneously from all four sides.   

2，After grouting begins, it must be conducted continuously without interruption, and the grouting time should be minimized as much as possible.   
3，Do not over-vibrate during grouting; in necessary cases, use bamboo strips or similar for guiding the flow.   
4，Each grouting layer should not exceed100cm。   
5，Grouting of longer equipment or track foundations should be done in sections. The length of each section shall be determined...7 meters is ideal.
6，If water leakage is observed on the surface during the grouting process, a small amount can be sprinkled.LGM dry material, absorbs moisture.

7，After the equipment foundation grouting is completed, the parts to be removed should be handled before the grouting layer has fully set.   
8，Throughout the grouting construction process until demolding, it is essential to avoid vibration and impact on the grouting layer to prevent damage to the unhardened grout.  
9，The horizontal distance between the template and the base of the equipment should be controlled atApproximately 100mm, for ease of grouting construction.
10，In case of slurry leakage during grouting, it should be addressed promptly.   
11，When the base grouting volume of the equipment is large, mechanical stirring should be used.Do not use high-speed mixers for blending.To ensure grouting construction.   
6. Maintenance
1，The average temperature during grouting should not be lower than5°C, within 30 minutes after grouting is completed, apply curing agent immediately or cover with plastic film and then cover with rock wool blankets, wet straw bags, etc. for maintenance, or immediately water the grouting layer to maintain moisture after the grouting layer has reached final setting. The maintenance period should not be less than 7 days.
2，During winter construction, maintenance measures should also comply with the current "Code for Construction and Acceptance of Reinforced Concrete Engineering."Regulations of (GB50204).
3，Curing and Demolding Time Tables at Different Temperature Conditions    

  4，The surface temperature of the cement-based grouting material after demolding is higher than the ambient temperature by more thanAt 20°C, the material should be covered with insulating material for maintenance.
  5，If the ambient temperature falls below the minimum construction temperature required for cementitious grouting materials or if an accelerated strength gain is needed, artificial heating and curing may be employed.                  Protection methods; maintenance measures should comply with the current national standard "Regulations for Winter Construction of Construction Projects"Regulations regarding JGJ104.
