| Abstract | ||||
| Mid-Tertiary volcanism in the Western Desert Egypt was associated with the opening of the Red Sea, a period of 30 Ma. Basalts are composed of plagioclase, pyroxene, and olivine minerals. Basalt used as natural volcanic pozzolans materials; represent large interest of researches as a real alternative to replace ordinary Portland cement (OPC). The present work was performed on six samples of experimental cement clinker, one with ordinary raw materials (limestone & shale) as a reference sample, and five others with various substance (limestone & basalts), which show the possibility of the utilization of natural pozzolan for maintainable construction material. The chemical, mineralogical composition and texture produced clinkers were determined by scanning electron microscopy (SEM-EDS), X-ray diffraction (XRD) and differential thermal analysis (DTA). It is concluded that the produced clinkers which made from basalt are coincidence ordinary Portland cement clinker. They are characterized by increasing in setting time, compressive strength and resistance to sulfate attack. | ||||
