Sika® Stabilizer Aquagel

1 year in original, unopened packaging.

Store dry at temperatures ranging between +10 °C and +27 °C (50 °F and 80 °F).

Concrete Placement in Underwater Applications

Concrete with Sika® Stabilizer Aquagel should be discharged at a depth of at least 610 mm (24 in) below the surface of calm water or at least three (3) times the maximum height of the prevalent waves when water is agitated (in order to avoid any rolling action).

Sika® Stabilizer Aquagel can be used in conjunction with other Sika® admixtures to achieve special concrete performance. When used with other admixtures, each admixture must be dispensed separately into the mix.

Effect on Slump
Adding Sika® Stabilizer Aquagel to concrete increases its cohesiveness and reduces its slump, making the concrete more difficult to consolidate. The slump loss is proportional to the dosage in Sika® Stabilizer Aquagel and can be as high as 125 mm (5 in) when used a high dosage.

It is highly recommended to offset the loss in slump by adding a High-Range Water Reducer (HRWR) such as any of Sika® Viscocrete® products. The HRWR can be added to the concrete before or after the introduction of Sika® Stabilizer Aquagel, however, optimum performances are obtained when the HRWR is introduced in the concrete before Sika® Stabilizer Aquagel. If additional slump loss would occur during transit or at the jobsite, re-tempering the load with additional HRWR will offset the slump loss.

Sika® Stabilizer Aquagel is recommended for use at 0.03 % to 0.25 % of cementitious materials (cement, fly ash, silica fume and slag). The dosage rate is dependent on:

• The slope for placing the concrete.
• The height of the fall.
• The force of currents.
• The height of the waves.

     
Note: Sika does not advise employing usage rates outside the recommended dosage range without consulting your Sika Canada Technical Sales Representative. Trial batches are suggested in order to determine the required dosage for optimum performance with your concrete components.
