Arm Grout NS 50 is free flow, Non-Shrink, high strength expansive grout for thickness of 100mm. It can with stands static load and dynamic load. It is based on Portland cement, graded aggregates and additives. The special additives used impart controlled expansion in the plastic state. The low W/C ratio ensures high Early and Final Compressive Strength. The flow characteristic of the grout fills the voids between the base plate and the concrete foundations completely and permanently. It effectively transfers all operational loads to the foundation.  Develops very high early and final strengths  Non-shrink material  Pre packed, factory blended  Non-metallic Free flow: it has excellent flow characteristics and has positive expansion during setting and ensures high level contact with bond area  Chloride free: it is basically a chloride free material and does not affect the steel or foundation bolts.
