Product Description

Product Application

This product is suitable for the joint grouting of industrialized residence ,prefabricated houses and components of bridge . It can also be used for secondary grouting of large equipment foundations, grouting of steel structure column angles , hanging plate lights and the other areas where require high strength and fluidity of the grout.


Sleeve grouting construction flowchart 

Check whether the grouting hole and the air outlet of the steel sleeve are blocked first,If any blockage,eliminate it.→ Connect the grouting pipe and prepare the plug. → Mix the water according to the recommended water consumption .Generally, we recommended to use a low-speed forced mixer and stir for 3-5 minutes; Since there are many bubbles after the hand drill stirring,we suggest you wait 2 minutes around till the bubbles broken and then continue the following steps. → The fluidity will increase with the stirring time under the condition of recommended water consumption. →Grout mechanically or manually from one end of the sleeve to the other end, then seal the grouting hole and air outlet → After grouting, do not disturb the grouting site within 24 hours.

Main Features

1)CGM-T800 SLEEVE GROUTING MATERIAL FOR REINFORCING STEEL BAR CONNECTION is a cement-based and dry-premixed material.

2) It is made up of high-grade cement, fine aggregate and various concrete admixtures

3) When it is used on site ,directly add water as per the project requirement to form a self-flowing slurry .
4) It has advantages of low viscosity ,good fluidity, high strength, strong adhesion, no shrinkage and so on.
5)Dosage: Add water: 15%-17% 

6)Packing: 25kg/bag, moisture-proof package
7)Usage: 2300KG/m3 (theoretical value)
8)Storage: It can be stored for 6 months under the condition of dry sealed bag . If stored more than 6 months,better test the properties before use it.
9)Durability:Strength does not change significantly after 200 fatigue tests and 50 freeze-thaw cycles tests.

Fluidity test chart

Mix and stir the grout 

1. Stir with a planetary cement mortar mixer, and wipe the stirring pot and stirring blade with a damp cloth beforehand; 

2.Pour the equipment foundation grout into the stirring pot, start stirring, add the metered mixing water in 10s (recommended water ratio 12.5%), and end the stirring for 240s according to the fixed procedure of cement mortar mixer;

Prepare tools and experiment bench 

1.Pre-cleaned the glass plate and the inner wall of the mold with a damp cloth ,then place the mold in center of the glass plate, and quickly poured the stirred grout into the mold. 

2.Prepare a metal truncated cone circular mold with smooth inner wall. The inner diameter of the mold lower mouth is 100±0.5mm, the inner diameter of the mold upper mouth is 70±0.5mm, and the height is 60±0.5mm;
3.Prepare a more than 500mm × 500mm glass plate and place it on the horizontal test bench;

Initial fluidity test and record data 

1.Lift the mold slowly, let the grouting material flows freely until it stops without disturbance. Then measure the surface maximum diffusion diameter and its perpendicular diameter with a caliper. After that ,calculate the average value as the initial value of fluidity and round the test result up to 1mm. 

2.Record the data.The initial value of the fluidity test shall be completed within 5 minutes from the start of the agitation to the end of the measurement;

30 minutes retention fluidity test.

1.After the initial value of the fluidity is measured, quickly fill the equipment base grout into the stirring pot, and cover the stirring pot with a damp cloth to prevent evaporation of water;
2. 30 minutes after the initial measurement of fluidity is completed, re-mix the equipment foundation grout in the stirring pot according to the fixing procedure of the mixer for 240s, then carry out the third and fourth clauses in A.0.1, and measure the fluidity value as the 30min retention fluidity . Keep values and record data.
