Description
Введенные добавки мела и соды обеспечивают разм гчение сырьевой массы в интервале температур 1100-1200 за счет образовани низкотемпературных легкоплавких эвтектик и газовыделени в период перехода массы в пиропластическое состо ние .The added additives of chalk and soda provide softening of the raw mass in the temperature range 1100-1200 due to the formation of low-temperature low-melting eutectics and gas release during the period of transition of the mass to the pyroplastic state.
Физико-механические свойства гранул, полученных на основе состава 1, содержащего (вес.%): отходы обогащени - 60,0; глина - 27, мел - 5, сода - 6 и с ганический газообразоват«ль - 2, и состава 2, содержащего: отходы обогащени 65 ,5; глина - 25, мел - 4, сода - 4, органический газообразователь - 1,5, приведены в таблиде.The physicomechanical properties of granules obtained on the basis of composition 1, containing (wt.%): Enrichment wastes - 60.0; clay — 27, chalk — 5, soda — 6 and with a ganic gas — 2 — and composition 2, containing: enrichment wastes 65, 5; clay - 25, chalk - 4, soda - 4, organic gasifier - 1.5, are given in the table.

Физико-механические испытани показьшают, что предложенньш новьш облегченньш заполнитель отвечает требовани м, предъ вл емым к керамзитовому гравию. Кроме того, по прочности и удельному расходу цемента бетоны на основе облегченного заполнител превосход т керамзитобетонъ аналогичного состава. Последнее вызвано .особым составом заполнител : низкоосновные кальциевые силикаты, составл ющие основу предлагаемого материала , на границе раздела реагируют с продуктами гидратации цемента.Physicomechanical tests show that the proposed lightweight aggregate meets the requirements for expanded clay gravel. In addition, in terms of strength and specific consumption of cement, concrete based on lightweight aggregate is superior to expanded clay concrete of a similar composition. The latter is caused by the specific composition of the aggregate: the low-basic calcium silicates, which form the basis of the proposed material, react at the interface with the products of cement hydration.
Следовательно, сохран существующий способ получени легкого заполнител , можно на основе отходов обогащени железных руд (железистых кварцитов) получить качественный легкий заполнитель .Therefore, preserving the existing method of obtaining a lightweight aggregate, it is possible to obtain high-quality lightweight aggregate based on iron ore (iron quartzite) enrichment waste.
