X Ray and Inductively Coupled Plasma Atomic Emission Spectroscopy Analysis of Cristallographic Structure And Composition of Pavement Based Clay Materials

摘要

In order to predicttechnological properties of local clay based materials mixed to wood waste and to prevent human health andenvironment, experimental mineral structure and composition study were conducted. The influence of wood waste on the structural properties of clay samples were also investigated. Non and stabilized clay sample at 4% of cement were made at different conditions and waste wood at different content have been incorporated. Mineralogical X-ray analysis was carried out using X- raydiffractometer with Geiger counter usingcobalt ?α radiationwith wavelength ????????Å. inductively coupled plasma atomic emission spectroscopy (ICP/AES) and inductively coupled plasma optical emission spectroscopy (ICP/OES) were used respectively to determine major, Minor and trace elements. The results showed that incorporation of wood waste has a strong effect on the crystallographic structure, making partially amorphous clay structure. It is found that the waste wood incorporating influence the lattice constants of the components of the clay and must be correlated to acid interaction. Chemical analysis of clay sample indicates kaolinite and SiOsub2/sub as a dominant clay minerals. The results has shown some trace and heavy metal contamination for human and environment.
