New-Generation Sealing Slurries for Borehole Injection Purposes

摘要: The development of techniques and technologies thanks to which parameters the ground medium can be modified makes specialists look for new recipes geopolymers – binders reinforcing sealing unstable permeable grounds. slurries are expected meet a number strict requirements, therefore it is important find admixtures additives could modify fresh hardened slurry. Special attention has been recently paid fluid ash by-product combustion hard coals. However, use this additive associated with application appropriate superplastifier. Laboratory analyses rheological ways improving their liquidity by properly selected third-generation superplastifier presented in paper. were based on Portland cement CEM I, milled granulated large-furnace slag fly from fluidized-bed coal.
