TECHNOLOGY OF CEMENT MORTARS MIXING REINFORCED CONTINUOUSLY BY THE MODIFIED MICROFIBER

Abstract

The use of the microfibres modified by carbon nanomaterials as the reinforcing component of
cement mortar is considered.Various technological schemes of the cement mortars mixing reinforced
continuously by the modified microfiber for receiving a cement and sand composition with
high strength characteristics are considered. The influence of continuously reinforced mortars mixing
technology on the uniformity of distribution of microfiber in mixture and strength indicators of
cement mortars is investigated. The optimum scheme of mixing which provides uniform distribution
of the reinforcing microfibre in a mortar mix and increase of strength characteristics of the mortar is
achieved.These obtained results will allow getting cement mortars with the increased maximum
strength at a bend for 33,5 % in comparison with the samples prepared according to the standard
scheme.
Keywords: cement mortars, technology of mixing, continuously reinforcement, modified microfiber.
