چکیده
A lot of energy is released during the cement manufacturing process, and a large amount carbon dioxide (CO2) discharged into environment. Presently, researchers are focusing on reducing CO2 emissions by researching sustainable alternatives to traditional Portland cement-based materials. comparative study material characterization both calcined agro-based waste ash (calcined ash) uncalcined (uncalcined its utilization as binder along with granulated blast furnace slag (GGBS) in alkali activation process carried out this paper. The regarding would help better understanding variation properties behavior process. tests conducted GGBS include specific gravity, X-ray fluorescence, diffraction, scanning electron microscopy, reaction degree, Brunauer-Emmett-Teller (BET) analysis, particle size distribution, Puntke test for microstructural characteristics. Later, alkali-activated mortars prepared using 30% weight (both uncalcined) 70% GGBS. comparison compressive strength was studied, which showed promising increase 11.02% mortar (23.46 MPa) 28 days when compared (21.13 MPa). major finding from indicates that shows results

Microstructural Characteristics of Geopolymers Based on Alkali-Activated Fly Ash
Aluminosilicate geopolymers with a high silica molar ratio have been prepared by mixing Croatian coal-ash (ASTM Class F) and sodium silicate solution (water glass, technical grade). The samples were cured at 85 °C for 8 h and 24 h in different experimental conditions. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM/EDS) have been use...

like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
