  cementing
In particular, the role of osmosis in well flushing and cementing processes was noted in study by N.
      
The described system not only allows cementing under vacuum, it also permits to optimise drainage during surgery.
      
HPCH is a composite system, which is composed of cementitious and auxiliary cementing materials, composite additives, abrasion resistance component (aggregate) and pigment.
      
The density of material structure, bonding capacity of cementitious material to the abrasion-resisting component and the corrosion resistance are greatly and effectively improved by adding the auxiliary cementing materials and compound additives.
      
Severe leakage is confirmed at the interface between hardened slurries and steel tube during the dynamically curing process, which induces the quick loss of cementing property of slurries.
