Structure and properties of hardened cement and concrete with addition of CSN-modifier

The results of investigation of the influence of carbon-silica nanomodifier (CSN-modifier) obtained by a sonochemical method from the product of joint grinding of fines from crushing schungite-containing rocks of the 3rd type from the Zazhoginsky deposit (Karelia) and anionic surfactant of naphthalene-formaldehyde type on the properties of cement paste, strength, composition and structure of hardened cement; physical and mechanical characteristics of fine-grained concrete.
