Pumped Concrete Systems

The design of a suitable concrete mix is essential so that the concrete is pumpable without segregation and blocking of the pipes. 

 

The critical factors influencing the pumpability of the concrete are:   

  • Low water content to prevent segregation and bleeding   
  • Optimised mix design with efficient use of fines and cements   
  • Cement and aggregate type   
  • Selection of correct consistence for application

 

With Sika® ViscoCrete® and Sika® Stabiliser technology it is possible to produce fresh concrete with the required consistence and good internal cohesion.

Friction and resistance in pipes is reduced, helping maintain pumping pressure at a more constant and lower level. Sika technology for pumped concrete allows the realisation of the most demanding and challenging concrete requirements on construction sites.

The successful construction of many structures is based on Sika technology, in combination with our experience in the development of the best mix designs.    

  • Sika® ViscoCrete® to reduce water contents, improve rheology characteristics and cement hydration efficiency  
  • Sika® Stabiliser to improve the internal cohesion properties of fresh concrete
