High Strength Pumpable Non-Shrink Cementitious Grout

Description StarGrout 2400 is a non shrink, cementitious premixed grout with extended working time to suit local ambient temperatures. StarGrout 2400 is based on a blend cements, carefully selected and graded aggregates and Star Admixtures. This precise blend of materials produces a grout which achieves high strength rapidly and is suitable for a wide range applications.

Uses StarGrout 2400 are used for grouting over a wide range of applications :- Machine bedding/base plates- Supporting bridge bearing pads- Precast Concrete Sections- Cavities, gaps and recesses- Dry pack application

Advantages - Excellent flowability- No metallic iron contents to cause staining- Chloride free ( Non – Corrosive )- Good dimensional stability- Easy to mix and apply- No bleeding or segregation- Final strengths > 57 Mpa

Packaging StarGrout 2400 are supplied in 25 kg/bag

Instruction for use

Surface Preparation Surface must be clean, sound and free from dust, oil, grease, cement laitance and any loose materials. For maximum bond, surfaces should be roughned. All surfaces must be well saturated clean water orior to application of StarGrout 2400.

Mixing Put measured quantity of water ( depend on the required consistency ) into an empty pail/drum. Slowly add the total contents of Star Grout 2400 while mixing. Mix continuously for 5 – 7 minutes to achieve an even consistency. A mechanical powered low speed grout mixer should be used for the best result ( may be area of places are biggest ), StarGrout 2400 can be added aggregates ( bauxite 0 – 2 mm or calcined silica ) 20% weight of grouting.

Placing Pour StarGrout 2400 from one side only to avoid air entrapment. Do not vibrate. Use suitable head box of 150 – 200 mm and maintain to grout head at all times to ensure a continuous flow. Twenty five minutes are considered as the ideal placing time.

Curing On completion of the grouting operation all exposed areas which are not to be throughty cured. This should be done after the initial hardening of the grout by continuous application of water and / or wet hessian, or by application of suitable curing membrane such as Concure P.
