Показано, что уровень основных физико-механических свойств бетона — плотность, устойчивость к трещинообразованию, долговечность и надежность можно улучшить использованием высокоэффективной комплексной химической добавки на основе поликарбоксилатных полимеров, модифицированных электролитами на основе катионов металлов I группы главной подгруппы таблицы Д.И. Менделеева, обладающих повышенной подвижностью и, как следствие, диффузионной способностью, а также эффективно использовать в качестве дополнительного компонента добавки нанодисперсии гидроксида кремния, которые отличаются уникальными свойствами, а, именно повышенной реакционной активностью.

Установлено, что исследуемая комплексная химическая добавка обладает суперпластифицирующим и реакционноактивным эффектами действия, которая не только повышает степень гидратации цемента, но и способствует образованию новых гидратных фаз, о чем свидетельствует значительное повышение прочности на растяжение при изгибе, а также значительное повышение химической стойкости бетона.

Показано, что использование исследуемой комплексной химической добавки повышает прочность на сжатие на 41 % и более, на 56 % повышается прочность на растяжение при изгибе, что способствует повышению трещиностойкости бетона.

Определено, что водонепроницаемость бетона увеличивается на 75 % и соответствует марке W14, морозостойкость повышается на 70 % до значения F2500 и химическая стойкость бетона повышается на 16 %, до значения Kх.с. l 0,93 и согласно ГОСТ 58895-2020 данный модифицированный бетон соответствует бетону повышенной химической стойкости.

По результатам физико-механических исследований бетон с комплексной химической добавкой целесообразно использовать и рекомендовать для изготовления верхнего дорожного покрытия автомагистралей федерального назначения.

This paper describes that concrete physical and mechanical properties such as density, crack resistance, durability and reliability can be improved with introducing a high-performance chemical additive based on polycarboxylate polymers modified with electrolytes based on group I metal cations of the main subgroup in D.I. Mendeleev’s table. These high mobility polymers facilitate their diffusion ability. It is recommended to use silicon hydroxide nanoparticle dispersion as an additional component as they have such unique properties as increased reactivity.

The superplasticity and reactivity of the complex chemical additive under study proved to increase cement hydration process and enhance the formation of new hydrate phases, which contributed to a greater bending tensile strength and chemical resistance of concrete. The use of this complex chemical additive increased the compressive strength by more than 41 % and the bending tensile strength by 56 %, which contributed to concrete crack resistance.

Concrete water resistance was proved to increase by 75 % and corresponded to W14 class while concrete frost resistance increased by 70 % to the value of F2500, and chemical resistance increased by 16 % to the value Kx.s. l 0.93. According to GOST 58895-2020, this advanced concrete corresponds to the concrete with increased chemical resistance.

According to the test results of physical and mechanical properties, concrete with this complex chemical additive is recommended to use in federal highway pavement construction.
