Rheological behavior of 3D printable cement paste: criterial evaluation

Study of the carbon nanomaterials synthesis on the cement binder

“…Studies [1][2][3][4][5][6][7][8][9][10][11][12] discuss the issues of synthesis of nanomodifiers on matrix components of composites (cement, sand, gypsum, zeolite, etc.) and consider the characteristics and growth stages of particles and new phases of the nanoscale range.…”

“…Nanomodifying agents considered in the literature differ primarily in the principles and mechanisms of synthesis, which directly affect the formation of additive characteristics: size, morphology, specific surface area, particles' interaction energy, as well as the effective dosage degree [7][8][9][10][11][12]. In terms of efficiency of nanomodifiers [7], varieties of synthesized materials with predominantly spherical, tubular and cylindrical structure prevail.…”

“…The use of nanomodifiers with a similar structure, such as silica particles [8,9], is complicated by the short period of effect, in particular the role of the crystallisationcentre, which is most often observed in the early periods of hardening (1 day) and is not fixed in later periods. On the other hand, when modifiers based on nanocarbon materials of different structures are applied, their presence is observed throughout the interval of composite formation from the beginning of setting to later terms of the material life cycle.…”
