Description

technical field

[0001] The invention relates to an inorganic nanocomposite material and a preparation method thereof, in particular to a cement-based nanocomposite material and a preparation method thereof. Background technique

[0002] Active nano-inorganic composite material is a kind of Portland cement as the main cementing material, which is reinforced and toughened by high-strength orthopedics, active nano-materials (powder and fiber) and metal fibers, and is formed after curing at high temperature or high temperature and high pressure saturated steam It is an inorganic composite material, which belongs to ultra-high performance cement-based composite material.

[0003] Ultra-high-performance cement-based materials were developed after the invention of Densified Systems Containing homogeneously arranged ultra-fine Particles (DSP) cementitious materials by H.H.Bache of Aalborg Cement Company in Denmark in the 1980s. H.H.Bache's evenly distributed ultra-fine and dense sy...
