The present paper reports analysis made on three different types of Iraqi cement LIBS collected from the Kufa and Mass plant using laser induced breakdown spectroscopy (LIBS). Since, the constriction is concerned a very important parameter consists in order to obtain the best signal intensity. Therefore, the optimization of the LIBS signal by varying both of the pulsed Nd:YAG laser of 1064 nm, laser energy of 80, 100 and 120 mJ and the different pressure values of (5-11)108Pa to made the pellet. The major and minor chemical elements identified of Iraqi Cement such as, Ca, Fe, Si, and Mg. The influence of the pressure of powder and compressed cements pellets on LIBS performance investigated. The result revealed that laser energy of 100 mJ and 6*108 Pa applied pressure were good enough to generate plasma from cement samples.
