MasterLife SRA 50 - A expanding plasticising admixture for cement, grout and concrete

Description

MasterLife SRA 50 is an expansion system, which compensates for plastic shrinkage and settlement in cementitious grouts. Supplied in powder form, MasterLife SRA 50 produces controlled expansion in cement grouts and maintains high water retention. 

It contains a water-reducing agent, which increases the workability of the mix with reduced water content, making a stronger grout. Full expansion is achieved before initial setting occurs resulting in a high degree of interfacial contact.

Where is MasterLife SRA 50 applied?

For bedding, jointing, duct grouting and void filling applications where the following characteristics are beneficial: 

• A cement plasticising and water-reducing agent to improve the free flowing properties of the grout at low w/c ratios 
  
• An expanding agent that increases the volume of the grout, which in turn eliminates shrinkage and settlement 
  
• A catalyst to control the rate of expansion and to ensure full expansion of the grout.
