Portland cement, special additives

6 months from date of production

Store in undamaged, unopened, original sealed packaging in dry conditions between +5 °C and +35 °C. Protect from direct sunlight, heat and moisture.

w/p = 0.345 (+23 °C)

8.5 - 8.75 L of water per 25 kg bag

Water to powder ratio min. 0.34, max. 0.35 range (w/p = 0.34 - 0.35)

~16.5 L / 25 kg bag

For small applications mixing by paddle mixer is possible, however trials to assess the efficiency of such mixing equipment should be conducted. Mixing procedure may vary depending on the mixing equipment. Add 80 % of the water to the empty mixing vessel and add the SikaGrout®-190 powder while mixing, continue mixing for 1 minute. Add the remaining water whilst mixing and continue for further 3 minutes.

For larger quantities use a high shear colloidal type mixer (1400 rpm), slow speed agitator and pump. Mix the required amount of water and powder in a controlled manner to prevent lump formation. Continue mixing for approximately 3 minutes after adding the powder, longer mixing may increase the mix temperature and lead to premature setting. Upon completion of mixing, the grout should be transferred to the agitator vessel, where it should not remain for more than 30 minutes.

Mixing Watchpoints:

• At higher temperature use chilled water and store the bags in a cool place, to keep the mixed grout temperature below 25°C
• Mixed grout should be transfer to the agitator through a 2 mm sieve
• Do not use excess water
• Do not use hardened or lumpy grout caused by torn or water damaged bags
• Do not mix by hand
• Discard any grout that has been left in excess of 30 minutes

Please contact your local Sika Technical Representative for further information.

In most applications SikaGrout®-190 should be pumped with a diaphragm, piston or progressive cavity type pump. The chosen pump should
provide a continuous flow of grout. The pump should be fitted with a pressure limiting device capable of limiting pressure below 2 MPa, hoses
and connections should be checked at such pressures prior to grouting start. In certain applications, it may be necessary to cool and pre-soak the duct / hole, care should be taken to blow out such fluid prior to grouting start.
Typically, inlets for grouting shall be at the lowest point and outlets at the highest. The consistency of the grout at the outlet should be checked prior to stopping of grouting operations.
Refer to Sika Technical Representative for specific installation advice.

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be mechanically removed.
