Influence of nanomodifiers on the properties of concrete

Abstract

It is expedient to use fine-grained concretes for production of thinwalled, densely reinforced and other designs at which manufacturing there is a restriction in the size of a filler. Such concretes are a multicomponent composite system and contain both fine-grained aggregate and fine aggregate, as well as Portland cement and highly effective superplasticizers, which act as deflocculants. Optimal use allows you to control the rheological properties of concrete mixtures. In this case, it is also possible to change the structure of cement stone at the macro level. This allows to provide specific properties that provide high operational reliability of structures made using nanotechnology, in particular with the use of artificial raw materials. One of the ways to modify the structure of fine-grained concrete is the use of micellar catalysis in the preparation of both dense powder concrete5 and other types of concrete.
