Utilization of coal fly ash from power plants II. Geopolymer obtaining
Environmental Engineering and Management Journal › Vol. 8 › Nr. 3 Abstract
Study of geopolymer is a developing field of research for capitalizing solid waste and by-products in the view of new materials achievement having characteristics necessary for using as cement substitute. Also, it provides a solution to many problems regarding environment, such as reduction of gaseous emissions and particles matter resulted from cement industry and raw materials economy.
In this paper, the experimental conditions for obtaining new materials on the basis of fly ash f... Autori: Maria Harja, , Maria Gavrilescu ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=25419
Study of morphology for geopolymer materials obtained from fly ash
Environmental Engineering and Management Journal › Vol. 8 › Nr. 5 Abstract
Geopolymerization is a continuous developing field of research for utilizing solid waste and by-products. It provides a solution to many problems where hazardous residue has to be treated and stored under critical environmental conditions. Consumption of fly ash in the manufacture of geopolymer is an important strategy in making materials more environmentally friendly. Fly ash has been chosen as a base material in order to utilize this industrial waste.

ELUCIDATING CHARACTERISTICS OF GEOPOLYMER WITH SOLAR PANEL WASTE GLASS
Environmental Engineering and Management Journal › Vol. 14 › Nr. 1 Abstract
This study examined the characteristics of geopolymer with solar panel waste glass. After 28 days of curing, the compressive
strengths of the geopolymer samples containing 10 mass % and 20 mass % solar panel waste glass were 63.3± 1.8 and 49.1 ± 2.2
MPa, respectively. The geopolymer sample with 10% solar panel waste glass exhibited a stronger reaction than that with 20%
solar panel waste glass, and the strength decreased as the amount of solar panel waste glass increas... Autori: HuiCong Hao ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=26621
UTILIZATION OF OIL-CONTAMINATED CLAYS AS CONSTRUCTION MATERIALS
Environmental Engineering and Management Journal › Vol. 14 › Nr. 12 Abstract
The objective of this study is to manufacture a geopolymer by replacing part of the metakaolinite by calcined oil-contaminated
clay (OCC) and investigate its properties. The effects of the calcination temperature, the mix design of the alkali activator, and
the degree of calcined OCC replacement on the properties of the geopolymer were studied. Evaluation of pozzolanic activity and
compressive strength as well as micro structure observation by SEM and XRD were performed in this stud... Autori: Huan-Lin Luo ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=26905
ELUCIDATING THE EFFECTS OF NANOSILICA ON THE CHARACTERISTICS OF ALKALI-ACTIVATED THIN-FILM TRANSISTOR LIQUID-CRYSTAL DISPLAY WASTE GLASS
Environmental Engineering and Management Journal › Vol. 17 › Nr. 2 Thin-film transistor liquid-crystal display (TFT-LCD) waste glass can be used as a raw material for producing geopolymers, because it contains large amounts of silicon and aluminum in its amorphous structure. The setting time and compressive strength were evaluated to determine the quality of the geopolymer product with various amounts of nano-SiO2 (0%–3%) and TFT-LCD waste glass replacement (0% - 40%). The microstructures of the samples were characterized using mercury intrusion porosimet... Autori: Kang Gao ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=27634
STUDY ON SOLID/LIQUID RATIO AND MICROSTRUCTURE PROPERTIES OF ALKALI-ACTIVATED METAKAOLIN-BASED GEOPOLYMER CONTAINED IN LCD WASTE GLASS
Environmental Engineering and Management Journal › Vol. 19 › Nr. 1 There are considerable environmental and health and safety concerns regarding liquid crystal display (LCD) waste glass because of the waste electrical and electronic equipment (e-waste) that is deposited in landfills. In current study, the effect of variation in LCD waste glass on the deconvoluted fractions of silicon centers of metakaolin geopolymers has been comprehensively investigated to discover the underlying mechanisms governing the performance. Solid/liquid ratio affects the kinetics of ... Autori: Kang-Wei Lo ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28146 |
