Abstract

Quarry (Manufactured) sand is used as fine aggregate in this research. Cement was replaced by silica fume (10% by weight) and Super plastidzer (varying percentage by weight of binder) was added for good workability. Normally the disposal of bottom ash from the thermal power plant leads to land pollution. Manufactured sand (M-Sand) was partially replaced (10% - 50%) by bottom ash in concrete to solve the disposal problem. Mechanical property such as compressive strength and Durability properties, such as water absorption, sea water and acid resistance, abrasion, chloride penetration of concrete mix (M60) were evaluated. The result showed that use of bottom ash slightly affects the durability properties of concrete.
