Abstract

The invention relates to pollutant-resistant compositions containing organopolysiloxanes. They are used for producing impermeable walls and similar ground seals introduced into the earth. This pollutant-resistant organopolysiloxane-containing composition comprises

(A) a salt of organic or inorganic acid and organopolysiloxane which has SiC-attached radicals containing basic nitrogen in amounts of at least 0.5% by weight of basic nitrogen, based on the weight of this organopolysiloxane,

(B) organosilicon compound containing basic nitrogen in amounts of from 0 to 0.5% by weight, based on the weight of this organosilicon compound,

(C) swellable clay minerals and

(D) hydraulic binder.

Claims

1. A pollutant-resistant organopolysiloxane-containing composition for producing impermeable walls, landfill linings and similar seals, particularly those set into the earth, comprising;

(A) a salt of organic or inorganic acid and organopolysiloxane which has SiC-attached radicals containing basic nitrogen in amounts of at least 0.5% by weight of basic nitrogen, based on the weight of the organopolysiloxane,

(B) an organosilicon compound containing basic nitrogen in amounts of from 0 to 0.5% by weight, based on the weight of the organosilicon compound,

(C) swellable clay minerals and

(D) hydraulic binder.

2. A composition as claimed in claim 1, further having,

(E) concrete additives, and

(F) fillers.

3. A composition as claimed in claim 2, wherein said composition is further diluted with water in amounts of from 10 to 50% by weight based on the total weight of the composition.

4. A composition as claimed in claim 2, wherein

(A) is present from 0.01 to 5% by weight,

(B) is present from 0.01 to 10% by weight,

(C) is present from 0.1 to 15% by weight,

(D) is present from 5.0 to 30.0% by weight,

(E) is present from 0.1 to 2.0% by weight, and

(F) is present from 45.0 to 85.0% by weight based on the total weight of the composition.
