Introduction

In recent decades, new generation concretes have been increasingly used in construction. Their distinctive features are multicomponent, adjustable in a wide range of operational properties and have high manufacturability. Concrete of this type is characterized by a reduced specific consumption of cement per unit of strength when its high values are reached, high energy efficiency and the ability to minimize or eliminate vibration when compacting a concrete mixture and heat treatment in the manufacture of products and structures. Active mineral admixtures are an important component of concretes. New generation concretes, in contrast to traditional ones, these admixtures are introduced into compositions with superplasticizers, which significantly increases their efficiency as a result of a significant improvement in the rheological properties of the cement matrix. As numerous studies have shown, the greatest effect is achieved when a highly active mineral admixture-microsilica is introduced into the concrete mixtures.
