Description

лируемую поверхность, например методом торкретировани .surface to be cast, for example by gunning.

После отверждени  она образует на поверхности водонепроницаемый и стойкий к сол м слой, имеющий повышенную прочность и малый капилл рный подсос.After curing, it forms on the surface a waterproof and salt-resistant layer that has increased strength and a small capillary leak.

Предмет изобретени Subject invention

Бетонна  смесь, например, дл  гидроизол ции солеотвалов калийного производства.Concrete mix, for example, for hydroisolation of salt dumps of potash production.

включающа  портландцемент, мелкозернистый заполнитель, воду и полимерную добавку, о тличающа с  тем, что, с целью повышени  прочности и коррозионной стойкости покрыти , а также уменьшени  капилл рного подсоса, она содержит в качестве добавки водную дисперсию сополимера стирола, 2-этилгексилакрилата и акриловой кислоты в количестве 1,5- 2,7% от веса портландцемента (в пересчете па сухое вещество).comprising portland cement, fine-grained aggregate, water and polymer additives, in order to increase the strength and corrosion resistance of the coating, as well as reduce capillary suction, it contains as an additive an aqueous dispersion of styrene copolymer, 2-ethylhexyl acrylate and acrylic acid in the amount of 1.5-2.7% by weight of Portland cement (in terms of PA dry matter).
