Beschreibung
Zusammenfassung:	FIELD: inorganic chemistry. ^ SUBSTANCE: invention refers to grouting mortars used for cementation of casing pipes, condensate or oil wells, complicated with loosely-coupled, hydro failure rocks, as well as oil-and-gas and water-and-gas saturated in section of various pressure values. Technical result of invention lies in development of lightened grouting mortar with high sedimentary stability and improved cement stone resistance. Lightened grouting mortar contains the following composition, mass.%: oil-well portland cement 48.8-51.8, silica-alumina hollow microspheres 5.8-9.1, Monasile 0.6-1.2, water 39.4-41.2. ^ EFFECT: production of lightened grouting mortar with high sedimentary stability and improved cement stone resistance. ^ 1 tbl, 1 ex
