Development of Fly Ash Based Geopolymer As Anti Erosion Coating

Rapid development of marine resources increasingly demands the huge range of concrete coastal structures and offshore structures. However, the concrete exposed in rigorous marine environment is readily damaged by the erosive ocean-atmosphere and seawater. Besides, erosion also happens because of...
