(54) СТРОИТЕЛЬНЫЙ РАСТВОР(54) BUILDING SOLUTION
Порошкообразный минеральный наполнительОстальное . Пластифицирующа добавка - водный раствор омыленного в м гких услови х полиакрилнитрила (ТУ 01-68 препарат К-4) или гидролиэованный полиакрилнитрил (ТУ 6-01-166-74) имеет следующие свойства: нетоксична, легко растворима в водных системах, негорюча, недифицитна , биостойка, обладает высокими клеющими свойствами. Стоимость 130-360 руб. за 1 т.Powdered mineral fillerEverything. Plasticizing additive - an aqueous solution of polyacrylonitrile saponified under mild conditions (TU 01-68 preparation K-4) or hydrolyzed polyacrylonitrile (TU 6-01-166-74) has the following properties: non-toxic, easily soluble in aqueous systems, non-flammable, not deficient , biostable, has high adhesive properties. The cost of 130-360 rubles. for 1 t.

Каждую смесь приготавливают в турбулентном смесителе при загрузке материалов в следующей последовательности: жидкое стекло, пластифицирующа добавка , кремнефтористый натрий и наполнитель , перемешивание происходит в течение 2-3 мин.Each mixture is prepared in a turbulent mixer when loading materials in the following sequence: liquid glass, plasticizing agent, sodium silicofluoride and a filler, mixing takes place within 2-3 minutes.
Консистенцию строительного раствора определ ют при неизменных прочностных характеристиках:The consistency of the mortar is determined with unchanged strength characteristics:

Чтобы обеспечить строительному раствору расплЬш 19О см без пластификатора, необходимо увеличить количество жидкого стекла в композиции на 7-10%, что приведет к значительным внутренним напр жени м .In order to provide a construction solution of 19.0 cm without plasticizer, it is necessary to increase the amount of liquid glass in the composition by 7-10%, which will lead to significant internal stresses.
