Shield back filling, Stabilizing solution, Cement Milk, Grout
Essential factor of Water based Stabilizing solution is stability for groove wall. Important specification of the shield back-filling agent is viscosity vs specific gravity balance and suspension properties. Ground construction method considered Aggregate blend, compatibility with the water quality and liquidity. Emphasis of Underground construction waterproof is viscosity and Emphasis of tunnel backfilling agent is cement formulation and Resistant cementitious. Function of bentonite depend on Water characteristics.
