| Research Abstract |
Methodology to construct environment-friendly and durable concrete structures in marine cold regions was studied. Coal ash that is a by-product in thermal power plants was used for cement and sand replacement in mixing concrete. In this way concrete with coal ash showed higher durability against salt attack and freezing and thawing cycles. Integrated design to achieve both aspects was proposed.
