    The durability of cement protective coat is strongly influenced by the conditions of setting and hardening process in bore holes at significant depth. The efficiency of sealing operation is the consequence of this durability, particularly in aggressive environment and variable geological conditions. In this work the standard properties of fresh and hardened grouts produced using the salt brine and mineral admixtures, exposed to water and highly mineralized solutions, will be reported. The grouts were made from metallurgical cement CEM III/A 32,5 and drilling cement WG with very low $C_{3}A$ content, below 3%. The results of porosity and gas permeability measurements, as a function of curing time in water and corrosive media, will be also presented.
