Non-shrink Grouting Material

CGM-T50 STANDARD NON SHRINKAGE GROUTING MATERIAL is formulated in precise test.It adopts cement as binding material, compounds with various admixtures and selected aggregates ,supplements additives with high fluidity, micro-expansion, and anti-segregation. The product has advantages of no shrinkage, micro-expansion, Self-flow, vibration-free, non-toxic, harmless, non-aging, no pollution to water quality and surrounding environment, good self-tightness, anti-rust and so on. It fundamentally changes the bearing force of the equipment base so that it can evenly bear the full load of the equipment, thus meeting the installation requirements of various machine, heavy equipment and high-precision machine tools....

Laboratory Test 

Test Item: Bleeding rate (with steel)

Test tools: 

1. Plexiglass container

 2.Steel strand

Test requirements:

1.7∮5 steel strand

2.The exposed height in the container is 10-30mm

3.Rest for 3h

Experiment process

Experienment item: New formulation test 
Division of the grouting model is based on its two characteristics: fluidity and early strength.Based on the demand of special construction ,the grout specifications usually need to adjust the ratio and additives to sttle the final formulation.

1. According to the strength of the grout, the grout is generally divided into four categories: H-40, H-60, H-80, and H-20H. 

2.The values of 40, 60, and 80 are the compressive strength after 28 days of grouting construction, and the unit is Mpa.  In actual construction, the strength of each type of grouting material will be greater than the theoretical value to ensure the quality and safety of the project. 

3. H-20H is a kind of early strength grouting material. The compressive strength reaches 20MPa 2 hours after construction. 


Laboratory Test

Test item: Standard curing test block
Test requirements: 
1.When the test piece is in the age of the test piece, take out the test piece from the self-supporting room and test it as soon as possible to avoid the humidity change.
2.Take out the test piece and check its size and shape. The opposite sides should be parallel. Measure the length of the edge to the nearest 1mm.

Laboratory Test

Test item: compresIve strength
Test tools:  

1.standard curing test block

2.Press or universal testing machine

Test requirements:
1.The loading speed of 0.3MPa/s~0.8MPa/s for concrete with strength less than C30; 

2.The loading speed for 0.5MPa/s~0.8MPa/s for strength greater than C30 less than C60; 

3. 0.8 for strength greater than C60 Loading speed of MPa/s~1.0MPa/s. 

4.When the test piece begins to deform near the damage, stop adjusting the throttle of the test machine until the test piece is broken, and record the damage limit load F(N).
