Дл определени марки в жущего ; приготовл ли образцы - белочки jxtxiG см из смеси с Вольским песком в.соотношении 1:3 (в жущее:Вольский песок). . Образцы готовили прессованием под нагрузкой 150 МПа в течение 3 мин при оптимальной влажности. Испытание проводили в водонасыщенном состо нии через 28 и 90 сут. Составы и их свойства представлены в таблице.with i Invention is related to the construction and operation of roads. Hydraulic to the living, containing blast-furnace slag, gypsum and additives are widely known. F 1 The closest to the invention of the technical essence and the achieved effect is a low-active agent comprising 91-96.2 wt.% Dump ferrochrome slag and 3.8-9. .% vanadium anhydride Yu. A disadvantage of the known compositions is not high enough strength. The purpose of the invention is to drive a proxy into a suspect. This goal is achieved by those that, for metallurgical slag and activator, contains house waste slag as metallurgical slag, carbide sludge I and phosphogypsum I as an activator, and additionally fly ash at e. The following ratio of components, wt.%: 33 Carbide sludge, Phosphogypsum Zola-ash 10-20 Blast dump-,: solid slag. Remaining Example. A series of mixtures of ingra- are prepared for the pretreatment. dientov. The raw materials (slag, fly ash, carbide sludge, phosphogypsum, dried at 150-220 ° C) were subjected to joint grinding 1 in the set corresponding. wear in a laboratory mill of type M-10 to obtain a specific surface area of 4000 cMVr and a residue on a sieve of 0.08 not more than 15%. The target surface was determined on a PSC-2 instrument. Then the mixture was sealed with water. The resulting low-active substance was tested according to GOST 310-76. . To determine the brand to the merchant; Prepared samples - squirrels jxtxiG cm from a mixture with Volsky sand in a ratio of 1: 3 (live: Volsky sand). . Samples were prepared by pressing under a load of 150 MPa for 3 min at optimum humidity. The test was carried out in a water saturated state after 28 and 90 days. The compositions and their properties are presented in the table.
