Project description

The West White Rose Project will be developed through a fixed drilling platform consisting of a concrete gravity structure (CGS), built by the SNC-Lavalin- Dragados-Pennecon General Partnership (SDP), and an integrated topsides facilities. SDP will be constructing the CGS in the Argentia Graving Dock, located on the Argentia Peninsula approximately 130 km from St. John’s, NL.

Challenges Encountered

Semi-lightweight concrete was used for buoyancy resulting in very strict requirements for Density. Concrete also had to be pumped great distances and heights. These attributes made for difficulty in mix designs.

Other points to be highlighted

  • After 3 rounds of lab testing in NL & Aggressive Competition from both Grace & BASF, we were awarded this project.
  • There is a difference between Hebron Project (120,000 M3) and this one (80,000 M3)  regarding the needed Equipment Service & Tech support
  • After the Installation of the two plants & the team has put a Great Effort to help the project team achieving the required performance and help in Troubleshooting
  • We were at the job site for a week and we were invited to test all of our Air products Vs Grace ..We have proved that we have the Best Products and Best Service.
  • As a result of our effort : we have improved our Relationship with Dragados global tech managers to help winning more projects in Canada and gain their Trust ; & we also are in better position to win more business from Lafarge , & all of Capital ready mix business in NL .

Why these products were chosen

High quality, excellent technical support and most cost efficient to complete the work required. Neither Grace or Master Builders were able to achieve the required results needed by the contractor, even though the concrete producer was experienced with both of those and not Sika.

products used

Sika® ViscoCrete®-2100

HIGH RANGE WATER REDUCING ADMIXTURE
Water Reduction: Sika® ViscoCrete®-2100 can be dosed in small amounts to obtain water reduction from 10−15 % and will achieve water reduction up to 45 % at high dosage rates. Sika® ViscoCrete®-2100 is suitable for all levels of water reduction. High Plasticity: The superplasticizing action of Sika® ViscoCrete®-2100 provides high-slump, flowing concrete that maintains excellent workability and may be placed with minimal vibration even at very low water cement ratio’s as low as 0.25.
Sika® ViscoCrete®-2100 plasticized concrete is highly fluid while maintaining complete cohesion within the concrete matrix to eliminate excessive bleeding or segregation.  
Extended Slump Life and Set Control: Sika® ViscoCrete®-2100 has been formulated to provide controlled and predictable extended slump life for periods of 60 to 90 minutes with normal set times.  
The combined high range water reduction and superplasticizing action of Sika® ViscoCrete®-2100 provide the following benefits in hardened concrete:   
  • Higher ultimate strengths allow for greater engineering design flexibility and structural economies
  • Reduced water cement ratios produce more durable, dense concrete with reduced permeability
  • Highly effective plasticizer reduces surface defects in concrete elements and improves aesthetic appearance
  
Sika® ViscoCrete®-2100 has been formulated to provide maximum water reduction and extended slump retention at low dosages.
