Sika Technologies for Durable Concrete

Sika has developed multiple technologies which are able to enhance the properties of concrete to deliver high strength and high performance in many different applications. SikaFume®-50 S is a modified concrete additive in liquid form based on Sika Silica Fume Technology which can change the rheology of concrete to allow it to be used in environments where performance demands are high – Learn more about SikaFume®-50 S.

With the extraordinary superplasticising capabilities of Sika® ViscoCrete® technology, it is possible to reduce the water content of the concrete significantly and extend its flowability. Sika technologies will ensure the achievement of all your specified placing and performance requirements, resulting in:

  • Prolonged service life of concrete structures
  • Lower costs for maintenance and refurbishment works
  • Improved appearance of the concrete surfaces
  • More satisfied customers

Sika technologies for early and high strength concrete

Strength in concrete is referred to as ‘initial/early strength’ or ‘ultimate/high strength’. The critical factors influencing the strength of the concrete are:

  • The type of cement
  • The concrete admixtures
  • The concrete temperature
  • The water/cement ratio

Sika® ViscoCrete®

Special Sika® ViscoCrete® products have been developed, which produce a significant increase in initial or ultimate strength due to the strong water reducing and plasticising effects of the Sika® ViscoCrete® technology. The production of early and high strength concrete with Sika® ViscoCrete® and/or SikaRapid® technology results in significant advantages:

  • Faster construction time
  • Development of most cost efficient mix designs
  • Lower concrete consumption (when thinner elements can be designed)
  • Improved site capacity by increasing formwork rotation
  • Improved service life of structure
