Phosphorite buildup from Phosphorites that negatively affect nature. The reuse of this waste is carried out in this study by replacing percentage of cement by Phosphorite (P) residue and gypsum (G). The cement of the Phosphorites and gypsum was replaced by the following percentages of weight: for masonry (0%, 5%, 10% 15%, 25%, and 50%), for concrete (0%, 10%, 25%, 35%, and 50%), number of samples (36 masonry samples , 30 cube samples, 20 cylinder samples, total 86 samples) Standard Resistance strength tests were carried out at (Asia lab – Irbid) to verify the strength of pressure in new mixtures. The results showed that replacing of cement by P residues and G increased the strength of masonry sample (MGPC-25%) by (42%). The results showed that replacing of cement by Phosphorite residues and gypsum increased the strength of concrete cubes sample (CGPC-25%) by (13%). The results showed that replacing of cement by Phosphorite residues and gypsum increased the strength of concrete cylinders sample (CYGPC-25%) by (20%). It is proposed to use Phosphorite residues and gypsum as an alternative to the cement by limited percentage, because increasing the gypsum percentage causing failures and weakness of concrete.
