Beschreibung
Zusammenfassung:	FIELD: oil and gas production. ^ SUBSTANCE: invention relates to composition of light-weight plugging material and can find use in construction and reinforcement of oil, gas, and other wells. In material containing Portland cement clinker (69-84%), gypsum (1-6%), and light-weight additive (10-30.2%) composed of microsilica, superplasticizer (S-3), and air-entraining reagent, said air-entraining reagent is sodium abietate and ratio microsilica/sodium abietate/superplasticizer S-3 is as follows: 100:0.05:(4-100):0.8:2. ^ EFFECT: increased assortment of light-weight plugging materials. ^ 2 tbl
