Synthesis and fracture toughness of macro-defect-free (MDF) cement
Macro-defect-free (MDF) cements were developed following work by the research group led by Birchall at ICI during the late 1970s and early 1980s. MDF cement is a cement-polymer composite seen to provide the high stiffness of a hydrated cementitious material with the high tensile strength of a …
