    The phosphate industry is facing serious environmental problems. This issue is caused by the waste after
    the extraction of the phosphate ore. The waste termed as phosphate washing waste (PWW) was filtered
    and dried at 105 {\textordmasculine}C for 24 h to remove the water. The dried PWW was milled, sieved in a 100 mm sieve
    and characterized by X-ray fluorescence (XRF). The resulting waste was calcined at 600, 700 and 800 {\textordmasculine}C, the calcined and uncalcined waste were investigated by X-ray powder diffraction (DRX), Fourier transform infrared (FTIR), simultaneous differential thermal and thermogravimetric analyses (DSC-TG) and scanning electron microscope (SEM). The PWW was activated with sodium hydroxide (NaOH) and sodium silicate to produce geopolymeric materials. It was found that the calcination temperature and the extra water added to the mixture to assure the good workability play an important role on the development of the system{\textquoteright}s workability and compressive strength.
