Abstract

Macro-Defect-Free (MDF) materials are cement-polymer composites exhibiting high flexural strengths and high toughness (for cement based systems). The incorporation of fibers into MDF composites has been found to offer the possibility of increasing both the ultimate flexural strength and toughness of MDF materials prepared using an ordinary portland cement-polyacrylamide matrix.

This paper examined the effect of fiber type and fine particles as a packing filler on the resulting mechanical properties. The incorporation of non-traditional materials (for MDF) into the MDF matrix is also discussed.
