The improvement is expected due to Pozzolanic reaction of the fly ash that runs more slowly but for longer time than in the case of pure clinker cement as described by (e.g. Helmuth, 1987 or Fraay, Bijen and de Haan, 1989). Half the mixtures were further modified by adding 0.5% of volume of polypropylene monofilament 54 mm long fibres Forta-Ferro.
