Self-Compacting Concrete with a Multifunctional Modifier
Abstract: It has been given the data of the influence of the multifunctional modifier content consisting of microsilica Stakhanov Ferroalloy factory dispersed in the superplasticizing admix environment based on polynaphthalene sulfonate, alkali activator and curing the binder – sodium hydroxide on the rheological properties of concrete mixtures and mechanical properties of the concrete was. It has been shown that the alkaline activator as part of multifunctional modifier allows partial replacement of Portland cement with ground granulated blast furnace slag, while increasing the compressive strength of concrete in the early and later stages of hardening. It has been found out that the concrete mix with a multifunctional modifier has higher workability (flow ability) and resistance to segregation.
Keywords: self-compacting concrete, multifunctional modifier, workability (flowability), resistance to segregation, limit of compressive strength.
