Это связано с физическим эффектом, который проявляется в том, что мелкие частицы обычно имеют более тонкий гранулометрический состав, чем портландцемент, и проявляют себя как микронаполнитель. С другой стороны, это может быть связано с их пуццолановой активностью, которая проявляется в способности кремнезема и глинозема взаимодействовать с гидратом окиси кальция и образовывать гидросиликаты и гидроалюминаты кальция. В данной работе активность минеральных дисперсных компонентов оценивали по теоретическому значению коэффициента гидратационной активности, который определяли по их химическому составу. Фактический коэффициент гидратационной активности рассчитывали по максимальному значению прироста массы дисперсных побочных продуктов промышленности путем поглощения этими добавками Ca(OH)2 из насыщенного раствора извести. Количественный и вещественный состав кристаллических соединений в побочных продуктах промышленности определяли одним из косвенных методов, а именно с помощью рентгенофазового анализа. Экспериментальными данными было установлено, что фактическая пуццолановая активность оказалась намного ниже теоретического значения, и поэтому побочные продукты промышленности расположились в такой последовательности: золошлаковая смесь - побочный продукт углеобогащения - доменный гранулированный шлак, что подтверждается результатами рентгенофазового анализа и согласуется со значениями предела прочности бетонных образцов при сжатии, испытанных в разный период твердения.</p></abstract><trans-abstract xml:lang="en"><p>The introduction of dispersed mineral additives has a beneficial effect on many properties of concrete. This is due to a physical effect, which manifests itself in the fact that small particles usually have a finer granulometric composition than Portland cement and manifest themselves as a “micro-filler”. On the other hand, this may be due to their pozzolanic activity, which is manifested in the ability of silica and alumina to interact with calcium oxide hydrate and form calcium hydrosilicates and hydroaluminates. In this work, the activity of mineral dispersed components was estimated by the theoretical value of the coefficient of hydration activity, which was determined by their chemical composition. The actual coefficient of hydration activity was calculated from the maximum value of the massgain of dispersed industrial by-products by absorbing Ca(OH)2 from a saturated lime solution by these additives. The quantitative and material composition of crystalline compounds in industrial by-products was determined by one of the indirect methods, namely, by X-ray phase analysis. Experimental data showed that the actual pozzolanic activity was much lower than the theoretical value, and therefore the industrial by-products were arranged in the following sequence: ash-slag mixture - coal-enrichment by-product - blast furnace granulated slag, which is confirmed by the results of X-ray phase analysis and is consistent with the values of the compressive strength of concrete tested in different hardening periods.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рентгенофазовый анализ</kwd><kwd>золошлак</kwd><kwd>шлак доменный гранулированный молотый</kwd><kwd>отход углеобогащения</kwd><kwd>пуццолановая активность</kwd><kwd>предел прочности бетона при сжатии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>X-ray phase analysis</kwd><kwd>ash slag</kwd><kwd>granulated ground blast furnace slag</kwd><kwd>coal enrichment waste</kwd><kwd>pozzolan activity</kwd><kwd>compressive strength of concrete</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Попов С.В.
