Application

Application Information

Dispensing

  • Ensure that SikaRapid® CC is thoroughly mixed prior to use.

Add SikaRapid® CC to the clean mixing water and stir thoroughly before adding to the mortar/concrete mix. The volume of SikaRapid® CC depends on the required setting time. For cement mortars it is advisable to use a 1:4 cement sand mix. For concrete, a minimum of 300kg/m3 cement is recommended, with a minimum 28 day compressive strength of 25Mpa.

  • Leak Plugging

Add approximately 3 parts fresh Portland cement to 1 part SikaRapid® CC and mix thoroughly until plastic consistency is achieved (+ 30 seconds). Form a plug and compress it into the cavity, applying pressure continuously for approximately 2 minutes until cement has set.

  • Rapid setting and Hardening

Add the SikaRapid® CC and water mixture to the dry cement mortar/concrete mixing thoroughly and quickly until a homogeneous mix is achieved. Place in position immediately. Do not apply loads or traffic for at least  6 hours.

Restrictions

When using SikaRapid® CC a suitable mix design has been taken into account and local material sources should be trialled.

SikaRapid® CC contains calcium chloride and should not be used in concrete or mortar which has reinforcing bars or comes into direct contact with steel.

SikaRapid® CC should not be added to dry cement.

SikaRapid® CC should be added with the mixing water or introduced at the end of the mixing process.

Before application, suitability tests must be performed.
