Fine-Grained Concrete for Repair and Restoration of Building Structures

Abstract:

It is determined that the active components of modern concrete are active mineral fillers, such as microsilica, meta-kaolin, ash-bearing or compositions from them, as well as superplasticizers. The optimal combination of these additive modifiers allows you to control the rheological properties of concrete mixtures and to modify the structure of the cement stone in such a way as to provide concrete properties that provide high operational reliability of structures. However, they have certain disadvantages that hamper their widespread use. The purpose of the research is to determine the effect of reaction powders applied simultaneously with colloidal surfactant, on the strength of powdered concrete and the rate of its formation.
