FIELD: chemistry, construction.
SUBSTANCE: base foundation contains in wt %: oil-well Portland cement - 95.0-98.0; polyamide fibre or polyamide fibre mix with chrysotile asbestos in proportion 0.3-2.0:1 - 0.5-4.0; superplasticiser - 0.05-0.2; oxyethyl cellulose - 0.1-0.5; setting time accelerant - the rest. Additionally, base foundation may contain antifoamer in amount 0.1-0.2 wt %. As antifoamer base foundation contains POLYCEM DF, as superplasticiser, the superplasticisers of trade marks CEMPLAST MF, C-3, or Melflux, and as setting time accelerant - calcium chloride or sodium chloride.
EFFECT: increase in quality of plugging stone formed due to mechanical properties improvement.
