Self‐Assembly of Organic–Inorganic Copolymers Toward Bio‐Inspired Cementitious Composites
Organic–inorganic copolymerization of calcium silicate hydrate and thioctic acid produces a self‐organized nanocomposite inspired by the disordered collagen–mineral architecture of trabecular bone. The resulting material combines a compressive strength above 300 MPa with intrinsic physical reprocessibility, retaining over 80% of its strength and energy

Influence of fracture process zone height on fracture energy of concrete
Cement and Concrete Research, 2004Abstract The implication of modelling concrete fracture with a fictitious crack of zero fracture process zone (FPZ) height is addressed because FPZ height, in reality, is not zero and is bound to vary during crack growth. The ligament effect on fracture energy G F is explained by the nonuniform distribution of a local fracture energy g f ...
