Total of 36 sample was prepared by cutting the cube specimens which is a new suggested method for preparing the samples.
Different volume fractions of polypropylene (PP) fibre and various thickness were investigate.
There was a strong linear relation between volume fraction of PP fibre and impact resistance as well as crack resistance ratio and this relation was indefeasible by changing the thickness from 20 mm to 30 mm and 40 mm.
Increasing the thickness improves the impact resistance significantly, but the effect was more pronounced for ultimate failure crack resistance than the first crack resistance.
The optimum ductility has been offered by specimens with 0.3% VF of PP fibre and 30 mm thickness.
