    ​MasterRoc AGA 155 - Plasticising admixture with set retarding properties for use in annular grout mixes for TBM tunneling


    ​MasterRoc® AGA 155 is a liquid plasticiser which disperses and deflocculates cement particles whilst delaying the hydration process, thereby retarding the initial and final set. It can be used to improve workability without the addition of extra water, or to allow reductions in the free water content. Due to improved dispersion of the cement pa rticles the process of hydration proceeds under the optimu m conditions, leading to improved strength characteristics w ith or without reduction in free water.


    -High flow, low cement content, high W/C ratio annular gro ut mixes. ­
    -Hot weather applications of grout where control of initial a nd final set is important.
    -Retarded mortars (also in combination with Rheomix 910) 


    Setting control of annular grout mixes for injection behind segmental tunnel linings. MasterRoc® AGA 155 is designed for use in one or two component grouting systems and is compatible with accelerators such as MasterRoc ® AGA 370. ​
