SikaGrout®-9300

(former MFlow 9300)

Ultra high strength, cement based grout with metallic aggregate and applied nanotechnology for grouting onshore wind turbine installations  

SikaGrout®-9300 is a shrinkage compensated, cement based grout which when mixed with water, produces a homogeneous, flowable and pumpable grout with exceptionally high early and final strength and modulus. The product contains special metallic aggregates for increased ductility, fatigue and impact resistance. Latest best binder packing models and applied nanotechnology produces a grout with superior technical performance, exceptional rheological properties, and, uniquely, extended open times.

  • Ultra high compressive strength >120 MPa.
  • Ultra high modulus for exceptional stiffening properties.
  • Excellent fatigue resistance. 
  • Quick return to service and removal of temporary supports due to high early strength build-up. ≥ 60 MPa @ 24hrs at 20°C
  • No segregation or bleeding to ensure consistent final physical performance and to prevent pump blockages. 
  • Contains metallic aggregates to provide increased resistance to dynamic and repetitive loading
  • Pump able over long distances and large heights.
  • Extended pot life of ≥ 2 hours
  • Can be pumped into complex areas or areas inaccessible to conventional grouting methods
  • Specially graded sands and exceptional flow and low friction increases pump output, reduces installa-tion times and costs as well as reducing pump pres-sures and wear
  • Dust reduced for ease of handling
  • Cement based.
  • Low chromate.

Usage

SikaGrout®-9300has been especially formulated for: 
  • Grouting of wind turbine installations, e.g. base plate grouting of onshore wind turbines, where excellent fatigue resistance is required
  • Grouting under very harsh conditions, e.g. temperatures as low as 2°C.
  • Anchoring anchor bolts of wind turbine towers
  • All void filling from 30mm to 200mm where high strength, high modulus, high ductility is important (for other void dimensions contact our technical department).
Contact the Technical Department of your local Sika office regarding any application or dimensions required not mentioned here.

NOTES ON INSTALLATION

  • SikaGrout®-9300 has been especially formulated for use in specific applications. As such SikaGrout®-9300 should be installed by experienced fully trained contractors. Full application procedures are available on request.

  • Sands or other products that could affect the prod-ucts properties must not be added.

  • SikaGrout®-9300 which will be exposed to strong drying conditions, e.g. mortar which is directly  exposed to heavy wind and/or direct sunlight, should be protected with moist cloth or plastic foil, or by using appropriate curing agents.

  • The temperature of the grout material, mixing water and elements coming in contact with the mixed grout should be in the range of +2°C to +30°C

  • When grouting in environments below +2°C or above +30°C contact the Technical Department of your local Sika office.

Application method

One continuous pour

SUBSTRATE PREPARATION

Concrete substrate preparation:

Clean out bolt holes and have the foundation area to be grouted thoroughly clean, rough but level. Saturate the cleaned foundation and any bolt holes with plenty of water. Remove all free standing water just prior to grouting. Always first grout the anchor bolts into the clean, damp (no free water) bolt holes.  

 

Formwork preparation:

Build strong, tight, well-braced formwork. On the grout placing side, slant the form outward and  extend this form suitably high to provide a head of grout during placement. Grout should be pumped directly on the sloped form to minimize air entrapment during  placement. Use methods of forming that will allow the grout to flow by gravity between the plate of the windmill tower and the foundation. Keep the grout in full contact with these  surfaces until it has hardened.  

MIXING

Do not add cement, sand or other materials that affect the properties of this quality-controlled product. Mix full bags only. Use one or more mixers (forced action pan mixers are advised) to permit mixing and placing operations to  proceed simultaneously without interruption. Mix with potable water only. Put ¾ of the water required in the first mixer and add slowly the grout material.  Mix until a homogeneous mortar (3 to 4 minutes), add the remaining water and continue mixing for at least  another 2 minutes until the required fluid or flowable  consistency is obtained  

APPLICATION

Mix and place the grout as close as possible to the area to be grouted. Have sufficient manpower, materials and tools to make mixing and placing rapid and continuous.  SikaGrout®-9300 may only be pumped into the area to be grouted. The grout shall be placed continuously and from one side only, to avoid air entrapment while grouting. Make sure grout fills the entire space to be filled and remains in  contact with the base plate and foundation throughout the entire grouting process. DO NOT VIBRATE SikaGrout®-9300.

 

CLEANING

Tools and spillages can be cleaned with water while SikaGrout®-9300 is still uncured.  Once hardened, the material can only be removed mechanically.
