Results of an investigation of the use of high-aspect-ratlo mica flakes in hardened portland cement matrices are reported. Increases in flexural strength by a factor of 2 and in fracture toughness by a factor of 4, depending on matrix porosity, are obtained by the addition of small amounts of mica.
To determine how the surface modification of mica influences flexural strength and fracture toughness of mica-relnforced cement composites, mica was treated with HF acid and three coupling agents: two silanes (CVBS, yMPS) and a titanate (IDT). Significant increases in mechanical properties resulted,
