Conclusions
By understanding the microstructural properties and parameters a wide variety of cement based composite laminates may be produced.
Tensile strengths of the order of 50 MPa and strain capacity on excess of 1% are possible.
Polymeric and synthetic fibers alter the energy absorption properties of the composites significantly.
Theretical modeling of FRC Materials using FEM, and non-linear fracture mechanics, and mechanics of composites allows a better utilization of the materials.
Uniform fiber distribution at various size scales improves composite performance, as the specific fiber spacing decreases, the strength of the brittle matrix is increased (Romualdi and Batson).
Small microfibers stabilize the microcracks and increase the strength. Reduction of the porosity of the cement paste as well increases the strength.
