MasterRoc MP 323
SOLVENT-FREE, LOW VISCOSITY, HYDROPHILIC GROUT FOR ROCK INJECTION AND CONSOLIDATION OF SANDY AND SILTY STRATA
Description
MasterRoc MP 323 is a sodium stabilised colloid of silica oxide nanoparticles in a sol form. By adding a second accelerating component to the sol the negatively charged nanoparticles can be made to collide and coalesce to form an impermeable stiff gel. The product is suitable for pumping as one-component or as two-components with in-line mixing.
Uses
Ground improvement
– Permeability reduction
– Strength increase
– Stabilisation of fluvial sands and silts
– Reducing risk of liquefaction
Low pressure permeation grouting of granular materials:
– TBM launching and reception shafts
– Preinjection prior to X-passage excavation
– Toe grouting and curtain grouting of ERS
– Plug grouting of shafts and boxes
– TAM (Sleeve) grouting with double packers
– Lance Grouting
Fissure grouting of rock strata to permanently reduce water ingress:
– Preinjection of shafts and tunnels
– Toe grouting and curtain grouting of ERS
Advantages
Very low viscosity ensures excellent permeation at low pressure.
By varying the accelerator dosage consistent and precise gel times for periods of between a minute to days are possible, ensuring complete filling of voids and a reduction in losses due to gravity.
Both components are non-toxic and the product is suitable for use in most environmentally sensitive areas.
Hydrophilic properties ensure good bonding to wet surfaces.
Stable and continuous strength gain over time.
Very little syneresis in wet conditions.
Simple mixing and handling on site.
