The utilization of industrial waste as a construction material is a big leap towards sustainable development. Flyash is a waste material obtained from thermal power plants during combustion of pulverized coal. Though there are many practices to use flyash as a construction material in past few decades; manufacturing of sintered flyash aggregate is Microwave sintering of carbon fly ash containing garnet ,Carbon fly ash containing NaCl and garnet was sintered using microwave irradiation. A cavityresonatorcontrolled microwave field (TM020) was applied, and cavity perturbation methods were used to measure the electrical permittivity of the fly ash at temperatures in the range of 25–700 °C.(PDF) Replacement of Coarse Aggregate with Sintered Fly ,The highest flexural strength9 of 11.16 N/mm was obtained at 30% Sintered fly ash aggregate replacement in concrete, whereas the lowest strength of 2.10 N/mm was observed at 50% Sintered fly ash

Experimental investigations have been carried out to study the mechanical properties related to the strength of concrete, namely, compressive strength, split tensile strength and flexural strength with sintered fly ash aggregate as fine
At this moment, the carbon in the fly ash was completely oxidized and the black color was disappeared. After sintering at 900 °C, the fly ash had lighter in color than that after sintering at 670 °C. The ash particles were agglomerated, producing bigger size. The SEM of raw HFA and sintered ash are shown in Fig. 8 and Fig. S2 –Fig. S4.

The specific gravity of sintered fly ash aggregate is increased from 1.51 to 1.92 when it is exposed higher temperature to 1200oC from 11000C [23]. The density of the sintered fly ash aggregate also is increase at a higher temperature from 10750C to 12000C [6]. The sintered fly ash aggregate specific gravity or density start to decreasing until theon Sintered Fly Ash and Modified with Exfoliated ,successfully replaced by waste materials [3–5]. An example of such material is sintered fly ash (SFA). Fly ash is one of the byproducts of fossil fuels (especially hard coal and lignite) combustion.
