Cable Grout Additive
Vetogrout GA514 is a preblended powder admixture containing expansive agents which impart controlled expansion in the plastic state whilst minimising water demand. The material is designed to allow uniform mixing, and eliminates unwanted segregation and bleeding.
- BS EN 445
- BS EN 196
Vetogrout GA514 is supplied in 24 kg Bag
Original sealed bag of Vetogrout GA514 has a shelf life of 12 months provided it is stored clear of ground in a dry and shaded place.
Mixing
For best results a mechanically powered grout mixer should be used. Do not use a colloidal impeller mixer, if sands/aggregates are being used. To enable the grouting operation to be carried out continuously, it is essential that sufficient mixing capacity and labour are available. The use of a grout holding tank with provision to gently agitate the grout may be required.
33 to 38 litres of clean water (depending on nature of cement) and 100 kg of cement are required to be added per 6 kg bag to achieve the correct consistency.
The water should be accurately measured into the mixer. The total contents of the Vetogrout GA514 bag should be slowly added with the cement and continuous mixing should take place for 5 minutes. This will ensure that the grout has a smooth even consistency.
Placing
Place Vetogrout GA514 mix within 20 minutes of mixing in annular gaps of up to 60 mm thick. A screw feeding pump such as PFT ZP3 booster pump or equivalent can be used.
Curing
Use standard curing practices as per ACI recomendation to cure any exposed surfaces of the placed mix bu use of a curing compound such as Vetocure XT425.
Cleaning
Tools and equipment can be cleaned with fresh water. Hardened material needs to be removed mechanically.
Preparation
Several hours prior to grouting, the area should be flooded with fresh water. Immediately before grouting takes place any free water should be removed.
All cable ducts must be thoroughly cleaned. Those ducts formed without metal sheaths should be flushed with water after which all surplus water must be removed. Cable anchorages should be sealed before the duct grouting is carried out.
Design Consideration
Vetogrout GA514 os tested using 50 mm cubes. The mixture design shall be based on the following to achieve required results:
Sampling Procedure
Vetogrout GA514 is alkaline and should not come into contact with skin and eyes. Avoid inhalation of dust during mixing. Gloves, goggles and dust mask should be worn. If contact with skin occurs, wash with water. Splashes to eyes should be washed immediately with plenty of clean water and medical advice sought. Vetogrout GA514 is non-flammable.
