MasterLife SRA 70 - Expanding plasticising admixture for cement and grout

MasterLife SRA 70 is an expansion system which compensates for plastic shrinkage and settlement in cementitious grouts. Supplied in powder form, MasterLife SRA 70 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 a reduced water content, making a stronger grout. Full expansion is achieved before initial setting occurs resulting in a high degree of interfacial contact.​

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 water/cement ratios.

- For post tensioning of cables

- 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. (For precision grouting and load bearing operations use MasterFlow grouts.)
