Information

Crocodile CG Grout It is a ready-to-use fluid non-shrink grout with high compressive strength specifically for applications where grout is to be poured into restricted spaces. Typical applications include support of structural elements such as precast walls, beams, columns and panels.

How to use

Substrate Preparation

  • All loose and unsound concrete must be removed and surface should be roughened.
  • The concrete bonding surfaces must be thoroughly cleaned to increase the compressive strength. Remove the grease, oil, dirt, curing compounds or other contaminants.
  • Forms must be strong, securely anchored, shored and sealed to prevent grout leakage.
  • Surfaces should be moistened and preferably kept damp. Remove all excess or standing water from concrete immediately prior to grout placement.

Proportion of Mixing
  • Water per Product 25 kg
    Plastic 3.25-3.75 liters
    Flow able 4-4.75 liters
    Fluid 4.875-5 liters
  • Product : Water by Volume
    Plastic 5 : 1
    Flow able 4 : 1
    Fluid 3.5 : 1

Mixing
  1. Use the clean water to mixing by the proportion in a guide.
  2. Prepare the electric mixer.
  3. Fill the water in container and stir the electric mixer. Slowly add cement grout.
  4. After the grout is added continue mixing for approximately 2 minutes to ensure uniformity.
  5. In case of the grouting area are more than 3 inch should add gravel to mix with size no more than 3/8 inch (9 mm.) in the proportion of 25 – 50% by weight (5 – 10 kg per grout 20 kg.). If use the gravel to mix , should be increase the time to mixing for flowability of grout.
  6. Do not add more water after finish the mixing
Remarks : Should be mixing the grout in 30 minutes usage time and do not mixing the rest grout to use again.

Mixture Consistency
The proportion of mixing is the guideline. In fact , the key to measure the water to mixing is depend on temperature.Use less water as possible to get the great flowability and volume of grout.

Application
  1. Pumped using a piston type grout pump.
  2. Surface or concrete should be damp.
  3. Grout should be placed under structural elements continuously and from one side only to avoid the entrapment of air pockets.
  4. Poke the structural elements to let the grout cement fulfilled.

Curing
  • All grout surfaces should be kept damped for 3 days.
  • Avoid the surface get quake and high/low temperature for 3 days.

Estimated Coverage
Crocodile CG Grout 73 bag (25 kg) / 1 m3

Caution
  • Cement may cause injury to skin or eyes. Use of rubber gloves, dust masks, eye protection, and other safety equipment is recommended.
  • If contact with eyes occurs, flush immediately and repeatedly with water, and then contact doctor immediately.
  • Avoid contact with skin. Wash thoroughly after handling.
  • Keep out of reach of children

Storage
It should be kept in a dry place and the temperature is not too high to avoid product’s degradation. Use within 1 year from the date of manufacturing
