Abstract

The invention relates to the building materials industry and is intended to obtain a clinkerless slag in a twitch with low water content and slower setting times. The composition includes granulated blast furnace slag and as a titanium-magnesium production treatment facility in the following ratio, wt.%: Blast granulated slag 90.6-95.2

as a wastewater treatment plant titanium-magnesium production 4.8-9.4. The presence of a cake makes it possible to replace the process of setting into a holding: beginning 5.5-6.7, end 7.7-8.4 hours with compressive strength 26.7 and bending 8.7 MPa. The normal density of the test is 17.5-25.3% by volume. 2 tab.

Description

The invention relates to the construction materials industry and is intended to produce clinker-free slag in the living.

The purpose of the invention is to reduce the water demand of the mixture and slow down the process of setting the slant.

This goal is achieved due to the fact that in the composition of the binder, containing blast-furnace granulated slag and activator of hardening, the latter uses the cake of titanium-magnesium production treatment plants with the following proportion of ingredients, wt.%: Blast-granulated blast 90.6- 97.4; refining cake

structures of titanium-magnesium production 9.4-4.8. production

  P “wastewater of titanium-magnesium production at the stage of filtration of sludge purification facilities. It is a pasty product with a moisture content of 75-80%. Moist cake is pre-dried to moisture. - The cake obtained after drying is a 20PPG fine powder with a particle surface of 18000-20000 and has the following composition of dry mass, wt.%: CaCO3 50.7-59 O67 1Gp ° ° L: about:

  As for its chemical and mineralogical composition, it differs from the components of the well-known in question. that it contains a significantly larger amount of TiO ,, and there are also CaCO ,, CaCl, trace impurities

 These differences in the qualitative composition and quantitative ratio of the compounds appear to be favorable. conditions for the formation of an optimal structure in the 1 hydro hydro oraluminates, monosulfoaluminates ettringites, etc.), which leads to a decrease in the water demand of the mixture and slow down the process of seizure in the bulk of the cake in the proposed sobavava in the A 8 mas. with a lower content of the cake, there is no reduction in the water requirement of the mixture and the speed of setting.

Cake dosage is equal to 9.A wt.X. is maximal, since with an increase in the share of the cake, the grinding bodies stick to the surface

To compare the physicomechanical characteristics of the obtained recipient, tests were carried out according to the methods rOLl 310.1-76-31O.A-76. The brand is determined by the ultimate strength of samples of 4C mm tars from a cement: sand solution in a ratio of 1: 3 (by weight) after 7 and 28 days from the moment of their bending and compression of their halves.
