SikaControl®-760

Low Dosage, Crystalline Waterproofing admixture for concrete & mortars

SikaControl®-760 is a crystalline powder admixture for concrete to achieve high resistance to water ingress. It is based on a blend of Portland cement, processed silica sand and special catalytic agents which converts hydration by-products to solid crystalline formation in the water transporting capillary tracts and hydration pores.

  • Increased durability.
  • Reduced sulphate attack.
  • Reduced efflorescence.
  • Improved cohesion, reduce segregation.
  • Pumpabiity of concrete is greatly improved.
  • Improved surface finish.
  • Reduced shrinkage cracks in plasters
  • Do not reduce compressive strengths
  • Liquid – easy to use.
  • Low dosage – Economical.

Usage

SikaControl®-760 should be used in all structural concrete that is constantly or intermittently in contact with water such as sea walls, tunnels, basements, structural and precast concrete. SikaControl®-760 can also be used as crystalline waterproofing admixture for cement mortars and plasters. To waterproof structures such as:
  • Water tanks, Reservoirs
  • Building Basements & foundations  
  • Swimming pools and water parks
  • Sewage and Water treatment plants
  • Dams, canals, Tunnels, Harbours
  • Retaining walls & sea defence walls
  • Concrete pipes

Compatibility

SikaControl®-760 is compatible with most admixtures used in the production of quality concrete including normal, other mid-range and high-range water-reducing admixtures, air entertainers, accelerators, retarders, extended set- control admixtures, corrosion inhibitors, and shrinkage reducers.
SikaControl®-760 is also compatible with slag and pozzolans such as fly ash and silica fume.
Consumption

Recommended Dosage

As a guide, a dosage of 1000 grams per 100kg of cement content is recommended. Dosage up to 2000 grams per 100 kg of cement content can be used in special requirements. For addition to ready mix concrete, a dosage of 5 Kg per cubic meter is best recommended.
For addition information on SikaControl®-760 or on its use in developing concrete mixes with special performance characteristics, contact your local representative.
Points to remember when producing waterproof concrete

  • Ensure water / cement ratio is less than 0.5
  • Addition of good plasticiser from the Sikament® RB or Sika® ViscoCrete® range is advised to achieve mini-mum water/cement ratio.
  • Place concrete quickly and compact it well.
  • Ensure complete curing with a curing compound.
Application steps

APPLICATION

SikaControl®-760 is a ready-to-use powder which is dispensed into the concrete together with the cement. Following sequence of mixing shall enable best performing waterproofing mix:

  • Batch course aggregates
  • Batch fine aggregates
  • Batch cement & mineral admixtures
  • Sprinkle SikaControl®-760
  • Dry mix for 1 to 2 minutes to achieve even dry mixture
  • Add gauging water admixed with plasticiser (if required) and continue mixing to even consistency of the mix.

In case of addition at the batching plant, use a 5 Kg dosage per cubic meter and add separately after introducing all other mix ingredients in the mixer and ensure uniform mixing. The addition of SikaControl®-760 to gauging water is not recommended.
