SU709590A1 - Building mortar - Google Patents

Description

The invention relates to building materials and can be used in protecting equipment and pipelines from corrosion. Known mortar, including blast furnace slag and liquid glass 1). A construction solution is also known, including, in wt.%: Ground granulated slag slag 66 Liquid glass 20 Portland cement 9 Water5 12 The last of these solutions is closest to the described technical essence and the achieved result. The disadvantage of the known solutions is low strength and low chemical and abrasive resistance to abrasive salt slurries. The purpose of the invention is to increase the strength, chemical and abrasion resistance. This is achieved by the fact that the mortar, which includes ground granulated slag and liquid glass, additionally contains screenings of 1–5 mm granite rubble, fine silica and asbestos, in the following ratio, wt.%: .Die glass10-18 Screening of granite rubble fraction 1-5 mm4.0-37.5 Fine silica1.0-3.0 Asbestos 1.5-5.0 Example. Construction rast-. The thief is prepared as follows. Elimination of crushed granite fraction 1-5 mm is loaded into the mortar mixer, ground domain granulated slag fraction 0-0.63, asbestos is added. The mass is stirred, after which the water glass is introduced, then the mixture is again mixed until a homogeneous mass is obtained. During mixing, fine silica was introduced evenly. In tab. 1 shows the compositions of the described mortar and known solution. In tab. 2 shows the physico-mechanical properties of the described solution and known.

As can be seen from the retesting tests, the chemical resistance of the composition is 1.5 times higher, the abrasion resistance is 2.1 times higher, and the strength is 1.3 times higher than that of j of a well-known composition.

Claims (1)

Claim The mortar, including ground blast furnace granular slag and liquid glass, is distinguished by the fact that, in order to increase strength, chemical and abrasion resistance, it additionally contains screening of granite crushed stone fractions of 1-5 mm, finely divided silica and asbestos, in the following ratio, wt.%: Ground blast furnace granular slag Liquid glass 50-70 10-18 Screening of crushed granite fractions of 1-5 mm Fine finely dispersed silica Asbestos
