We present a method for producing complex nano-modified MWCNT -based additives , which consists in the preliminary preparation by suspensions of nanoparticles in the dispersion medium of isopropyl alcohol and then mixing them with surfactants. The resulting premix rate of 0.0005% from MWCNTs injected cement consumption in the cement paste. The results of studies of the structure of the CC -modified MWCNTs («Arcema», France), using an electron microscope and a PC "Structure" at the macro and mesostructural levels.
цементный камень (ЦК), многослойные углеродные нанотрубки (МУНТ), поры, трещины, новообразования, макро- и мезоструктура, cement stone ( CC ), multiwall carbon nanotubes ( MWCNTs ), pores, cracks, neoplasms, macro and mesostructure
