“…01-071-1166) and quartz (JCPDS: 00-046-1045). These crystalline phases were identified in the metakaolin and are not modified by the geopolymerization process [33]. Although the main contribution is observed in all the samples, it shows some minor differences in its shape from one sample to another, suggesting the presence of several amorphous networks.…”

“…To study the evolution of the various networks present in the binder, diffractograms measured at different times of consolidation and the XRD pattern of metakaolin are presented in Figure 3. The latter presents a broad dome centered at 24°, characteristic of its amorphous part and some peaks attributed to crystalline anatase (JCPDS: 01-071-1166) and quartz (JCPDS: 00-046-1045) [40]. Whatever the consolidation time, the binder's XRD pattern displays a broad dome at a slightly higher angle of diffraction, typical of amorphous material and the crystalline impurities identified in the metakaolin.…”

Materials such as ceramic matrix composites are developed for mechanical applications at high temperature, but their cost remains a limitation. Consequently, the use of acid-based geopolymer matrices may be an alternative to reduce costs. In this study, the sample was prepared from metakaolin and phosphoric acid. FTIR and NMR spectroscopies, XRD and thermal measurements were used to understand the structural evolution of acid-based geopolymers (binders) during consolidation and after thermal treatments. According to the results, the consolidation of the binder has been divided into four steps: the dissolution of the metakaolin, the polycondensation reactions forming AlPO 4 entities and hydrated phases, the breakdown of Si-O-Al bonds with formation of various hydrated silica *Manuscript Click here to download Manuscript: manuscript.docx Click here to view linked References

“…Geopolymer can be viewed as an economic zeolite which produced by reacting solid aluminosilicate with highly alkali hydroxide [8]. A unique structure of geopolymer which good in mechanical, chemical and thermal making them as alternatives for a variety of application [9]. The purpose of this review is to evaluate the potential of geopolymer used to remove dangerous heavy metal in wastewater treatment in the recent studies.…”

Abstract. Rapid development of advanced technology in Malaysia gave impact increasing in the accumulation of heavy metal every day in our daily life through wastewater. Long term exposure of human bodies to heavy metals susceptible to receives various infections and diseases. From an environmental and economic perspective, adsorption is acceptable process that can be applied in wastewater treatment. However, usage of activated carbon most acknowledged and costly adsorbents lead people to find an alternative to activated carbon. Several studies of physical properties of geopolymer make them gain attention to replace an activated carbon in the treatment of heavy metal. This paper review adsorption of heavy metal by using geopolymer.
