| ABSTRACT |
|
Fabrication of high strength structural concrete was investigated by using a mechanochemically Surface Treated Fly Ash(MSTFA) induced by mechanochemical processing through ball-milling of (90 wt% As Recevied Fly Ash(ARFA) + 10wt% cement) mixture, which was compared to the specimen fabricated by using As Received Fly Ash(ARFA) in terms with compressive strength and microstructures. The compressive strength of concrete specimen fabricated by using MSTFA represented 10-20% and 2-7% higher value than that for the case of using ARFA and BPFA in each cases. Increased compressive strength as above mentioned is considered to be caused by mutually increased affinity generated between cement and fly ash during mechanochemical processing. |
