Nanomodified cement composites for thin walled architectural structures

Abstract

Abstract The article presents the studies of the processes of structure formation in the system “cement-plasticizer - crude carbon nanotubes”, established the relationship with the parameters of the structure, physical-mechanical and operational properties of composite materials from the standpoint of physico-chemical mechanics of dispersed systems and shows the influence of processes on the physical-mechanical properties of cement composites. The plastic strength and physical and mechanical properties of nanomodified cement mortars and fine-grained concretes have been studied and it has been shown that the use of the developed composite materials should be used to obtain fine-grained concretes for thin-walled architectural structures.
