Abstract:
1. An ultra-high-performance cement nanocomposites in which nanomaterials are dispersed, obtained by blending with water a composition comprising: cementitious materials comprising cement and supplementary cementitious materials with minimum particle size smaller than that of cement at 5% to 70% by weight of cement, with the weight ratio of water to cementitious materials ranging from 0.10 to 0.55; nanomaterials comprising at least one of carbon nanofibers and graphite nanoplatelets at 0.01% to 5% by weight of cementitious materials; dispersants comprising at least one of polyelectrolytes and surfactants at 0.1% to 100% by weight of nanomaterials; aggregates with particle size ranging from 0.01 mm to 50 mm at 10% to 800% by weight of cementitious materials; at least one of fibers other than carbon nanofibers of 1 to 1000 micrometer diameter with length-to-diameter ratio of at least 10, and whiskers of 0.1 to 10 micrometer diameter with length-to-diameter ratio of at least 5, at a dosage ranging from 0.05% to 10% by weight of cementitious materials; concrete chemical admixtures.
