Значительными проблемами строительной отрасли, при общем увеличении объема производимых работ, являются дефицит и удорожание материалов в связи с введенными антироссийскими санкциями. В настоящее время динамично растущим в цене и необходимым в строительстве материалом является портландцементное вяжущее. Производство портландцемента отвечает более чем 7% эмиссии углекислого газа в мире и вызывает опасения по поводу экологической обстановки на окружающих территориях. Решением указанных проблем может стать создание геополимерного вяжущего гибридного состава с включением вторичных материалов металлургической и теплоэнергетической промышленности, подвергнутых щелочной активации. Проведено исследование с целью оценки степени влияния компонентов смеси, их содержания и условий твердения на механические свойства вяжущего. Показана возможность достижения требуемой прочности строительного материала без тепловлажностной обработки, что позволяет рассматривать гибридное вяжущее как аналог портландцемента.

Nowadays, one of the significant issues for the construction industry is the shortage of materials due to the increased volume of work, as well as their rising cost due to the recently imposed anti-Russian restrictions. The most dynamically increasing in price and the most required material in construction at the moment is Portland cement binder. Portland cement production is responsible for more than 7% of the world's carbon dioxide emissions and is a constant source of environmental concern in the neighbouring areas. The solution to these issues could be the creation of a geopolymer binder of hybrid composition from secondary materials of the metallurgical and heat and power industries by their alkaline activation. The purpose of the study was to assess the degree of influence of each mixture component, its content and curing conditions on the mechanical properties of the resulting binder. The results of the study show the possibility of obtaining the required strength values without heat and humidity treatment during the gaining of strength, which allows the hybrid binder to be regarded as an analogue of Portland cement.
