Изобретение относитс к способу обработки бетонных изделий и может быть использовано в промышленности строительных материалов.The invention relates to a method for treating concrete products and can be used in the building materials industry.
Известен способ обработки бетонных изделий , заключающийс в пропитке их водным насыщенным раствором карбоната аммони .A known method for treating concrete products involves impregnating them with an aqueous saturated solution of ammonium carbonate.
Цель изобретени - повыщение прочности и водонепроницаемости бетонных изделий. Эта цель достигаетс тем, что бетонные издели пропитывают 1-20%-ным водным раствором нитрит-нитрата кальци .The purpose of the invention is to increase the strength and water resistance of concrete products. This goal is achieved by impregnating concrete products with a 1-20% aqueous solution of calcium nitrite-nitrate.
Отформованные бетонные образцы - кубы размером 7X7X7 см, ЮХЮХЮ см и цилиндры диам. 15 см после термовлажностной обработки пропитывают 1-20%-ным водным раствором нитрит-нитрата кальци (ННК).Molded concrete samples are cubes 7X7X7 cm in size, UHYHYYU cm and cylinders dia. 15 cm after the thermal and moisture treatment is impregnated with a 1-20% aqueous solution of calcium nitrite (NOC).
Ниже приведены результаты испытапий образцов , хранившихс в 5%-ном растворе ННК в течение 28 суток (I) и образцов, хранивщихс в воде в течение 28 суток (II).Below are the results of testing samples stored in a 5% NNC solution for 28 days (I) and samples stored in water for 28 days (II).
