Рассмотрены механизмы реакций, протекающих между продуктами гидратации портландцемента и компонентами кислой золы уноса. Отмечается влияние кристаллографических дефектов зерен алита на его гидратационную активность. Сделан вывод о том, что твердые отходы сжигания углей (зола уноса) могут быть использованы в качестве частичной замены портландцемента в производстве бетона, что приведет к снижению выбросов СО2 в атмосферу и сокращению количества золы в отвалах.

The mechanisms of reactions between the hydration products of Portland cement and the components of acidic fly ash were studied. The role of crystallographic defects in alite grains on their hydration activity was noted. It was concluded that solid waste from coal combustion (fly ash) can be used as a partial replacement for Portland cement in concrete production, which would lead to reduced CO2 emissions and a decrease in fly ash accumulation in landfills.
