Crushed ceramic and crushed basaltic pumice source were used at three levels of fine aggregate cement replacements (40%, 50%, and 60%). This study has been carried out mainly to investigate the abrasion resistance, the chloride penetration depth and the compressive strength of concrete.
Crushed basaltic-pumice (scoria) aggregate was separated according to their size. It was sieved using standard sieves and separated into six group consisting of 0/0.25, 0.25/1, 1/2, 2/4, 4/8 and 8/16 mm. A combination of separated aggregate was obtained with such a grading that complied with the requirements of TSI 706 [14].
