Description

(54) BINDING

one

The invention relates to building materials and can be used in industrial and civil construction, as a finishing and decorative material.

It is known to contain, including alkali metal compounds, rock and blast furnace slag 1.

The disadvantage of it is low water resistance.

It is known to have 2 with the following ratio of components, wt.%: Main domain

granulated slag 60-80 15 Carbonate filler 10-30 Alkaline melt 10-15 A disadvantage of the known grip is relatively low strength, especially for bending.

The purpose of the invention is to obtain a visitor with increased strength.

The goal is achieved by the fact that 25 the ground, including slag, carbonate filler and activator, contains ground phosphoric slag and as an activator, carnale or bischofite, or mirabilite, or aster a-30

ntgt with the following content of components, wt.%:.

Ground phosphorous slag 29-48 Activator1.0-2.0

Carbonate carrier Rest As raw materials, granulated phosphoric slag is used, having the following chemical composition, wt.%; CaO 41.4-48.3; SFO 41, C1-44.0; 5.5-7.3; MgO 2.5-3.2;

Fejoy

Carbonate fillers - limestone, dolomite, marble, shell rock, white color up to 100% in comparison with BaS04. Moreover, regardless of the nature of the filler, the strength of the proposed idle is relatively the same. Salt activator, such as natural carnallite, bischofite, mirabilite, astrakhanite.

Dp of obtaining silicate white concrete from the specified binder prepared three compositions with the following ratio of components, wt.%:

Claims (2)

the filler The salt activator 2.0 P (the ingotting agent for the sily mixture is produced in the following way. The phosphorus slag is ground to a specific surface of 3000–3500 cm / g and the carbonate filler is up to 1000–1500 cm / g. Then the calculated carbonate and carbonate the filler is thoroughly mixed into a dry mix of the binder solution of the activator. At that, the water-solid ratio is 0.15-0.2. The first raw mixture is placed in the form of the size of cm and vibrated on a vibrating plaster with a frequency of 2800-3000 count / min and vibration amplitude 0.5-0, IB minutes Vibration duration 60 pp. Autoclave processing of samples is carried out according to the mode of 1.5 + 7 + 1.5 hours at an overpressure of 10 Krc / cM.vA., The strength of the proposed live and known is given in The table shows that the flexural strength is increased by 68 when compressed - by 25% compared to the known .. Continuation of the Table The invention Formula In general, including a putty, carbonate filler and activator, characterized in that Increased strength, it contains ground phosphoric slag, and as an activator - carnallite or bischofite, or mirabilite, or astrakhavit with the following content of components, wt.%: Ground phosphate salt vshak 29-48 Aktivizatsf1.0-2.0 Carbonate filler Else Information sources taken into account during the examination 1.
