·Fly Ash Cenospheres FACs are among the most valuable byproducts obtained from the burning of coal They are lightweight density 400 kg/m3 800 kg/m3 hollow and spherical in nature and
·One step conversion of coal fly ash yielded a product with 40 45 wt % of zeolite Na P1 Fig 2 Analysis of the process water sampled at regular intervals from the reaction vessel during the conversion of fly ash into zeolite showed that the concentration of silicon in solution reached a maximum of ca 10 000 mg/l before stabilizing at around 6800 mg/l
After that this material is compressed into the shape of a brick using a fly ash brick machine The manufactured bricks are left in the sun to dry Depending on the clay the drying process takes anywhere from 24 to 48 hours In this method clay can be combined with various chemicals or concrete to change the composition of bricks and achieve
·As well known a lot of unburned carbon is always contained in raw fly ash which is an obstacle to the utilization of fly ash [1 27] In concrete industry fly ash has been re utilized as raw materials directly [35 51] while there is a strict requirement to the content of unburned carbon content in fly ash is traditionally in the range of 2 12% while
