Description

(34) WATERPROOFING COMPOSITION 12 The invention relates to construction materials and can be used in the construction of roads, waterproofing and anticorrosion works. The known waterproofing composition 13, including, wt.%: Sulfur5-15 Sulfur-containing waste Production of sulfur by phase exchange66 Sawdust 10-15 Rubber crumb The closest to the invention of the technical essence and the achieved result is the waterproofing composition t2j, which includes a bit of sulfur, an organic additive - naphthalene and mineral water. Nitel - rock flour The components in the following ratio, wt%: Bitumen 15 Sulfur 50 Naphthalene 3 stone flour 32 drawback of these compositions is their low adhesion to the concrete surface.. The purpose of the invention is to increase adhesion to the concrete surface. The goal is achieved by the fact that the waterproofing composition, including bitumen, sulfur, organic additive and mineral filler, contains organic polyvinyl chloride as an organic additive and, additionally, waste production of a series of phase exchange in the following ratio of components. %: Polyvinyl chloride Waste from sulfur production by phase exchange Mineral to the Others filling Waste from sulfur production by phase exchange contains,%: sulfur 45, silicon dioxide 48, magnesium oxide 4 and calcium oxide 3.

Sulfur is in the form of monoclinic sulfur and combined with the listed

elements,

Sulfuric waste in the form of crumbled gypsum of various fractions have a specific surface of 1600,,:: density. 2; -15 bulk density rykh-; scrap condition 1400 kg / m.

The waterproofing composition is prepared as follows.

In a bath on a sand cushion, sulfur is melted and at a temperature it is added in small portions: sulfur-containing wastes, mix them until they are completely melted. In a separate bath, bitumen is melted, after dehydration, polyvinyl chloride is introduced into it and mixed until a homogeneous mixture is obtained, which is introduced into the sulfur melt. The resulting mixture is stirred for 3 minutes. Then, fill-1 tel warmed to f-14b C is introduced and mixed again for 2 minutes. The mixture is poured into molds on the roadway or in the seams of the lining.
