| Abstract | In order to better understand fly ash (FA) samples, the sedimentation curve and loss weight in burning process were studied to reveal the physical properties, and the component and surface characteristics were analyzed with TG-DTG, SEM, FTIR and XRD approaches. The results showed $SiO_{2},$ $Al_{2}O_{3}$ and $Fe_{2}O_{3}$ accounted for 79.61% of the total weight of FA samples, and the sedimentation process was finished at 30 min. The total weight of FA samples decreased with temperatures increasing, especially from 620 °C to 670 °C. At 643.5 °C, the DTG value was highest, reached to 0.06148 %/°C. SEM micrographs indicated the rough and holey surface on FA samples composed of particles with different structures and shapes. The representative products were quartz and aluminosilicate, -OH, Si-O-Si and O-Si-O were found on the FTIR spectra and XRD diffractogram. The achievements were of great importance for the future utilization of FA samples in wastewater purification. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
