Improved Characteristics

The paper deals with the development of composite binders for producing concrete with improved characteristics of gas, water and vapor permeability. The authors investigate the processes of composite materials formation in order of decreasing scale levels from macro to nanostructures. The criteria for optimization of the volume of dispersed additives in concrete are offered. The authors theoretically studied the technological features of the formation of hydrated cement stone structure. A positive effect of nanodispersed additives on the structure and physico-mechanical properties of cement composite materials are predicted. Thanks to its improved features, such as good ratio of strength and body density, high density and lifetime, the modified concrete may be used when solving various practical tasks of the construction branch.

Pan Fibers

ABSTRACTA series of fiber-cement composite materials was prepared by dispersing different amounts of polyacrylnitril (PAN) fibers in portland cement suspensions of variable water/solid ratios. The samples were used to study the effect of the volume of fibers and the water-cement ratio on the physico-mechanical properties of the material. The distribution of the fibers within the cementitious matrix and the fracture mechanism were studied by SEM and compared with those existing in glass fiber-cement composites.
