Zusammenfassung:	oil and gas production. SUBSTANCE: aqueous composition containing 38.78-51.58% Portland cement, 6.39-17.80% thinning and expanding additive (hollow microspheres with 80-90% aluminosilicate component) additionally includes 10-20% aluminum hydroxychloride. EFFECT: achieved expansion effect in early period of cement stone formation owing to increased sedimentation stability of solution. 2 tbl
