Deterioration of Concrete in Ambient Marine Environment (RESEARCH NOTE)

Structural concrete exposed to marine environment deserves special attention as the diffused sea salts chemically react with harden cement matrix and forms various expansive/leachable compounds leading to loss of material, strength, cracking, spalling etc. This study cover the effect of sea water on the specimens cast from two grades of concrete exposed to simulated marine environment over a ye...

Plastics in the Marine Environment

“If all the plastic had been made with oxo-biodegradable technology there would be no ocean plastic garbage patches. ” In the 2012 study published in the Marine Pollution Bulletin “Occurrence of micro-plastics in gastrointestinal tracts of pelagic and demersal fish from the English Channel” it was shown that the majority of plastic particles consumed by the fish were rayon (57.8%) and polyester...

Microplastics in the marine environment.

This review discusses the mechanisms of generation and potential impacts of microplastics in the ocean environment. Weathering degradation of plastics on the beaches results in their surface embrittlement and microcracking, yielding microparticles that are carried into water by wind or wave action. Unlike inorganic fines present in sea water, microplastics concentrate persistent organic polluta...

Plastic in the Marine Environment

Plastic is cheap, ubiquitous and persistent. In 2010 the world produced 265M tonnes. Annual output is increasing with new uses and varieties augmenting demand. Plastic persists for centuries, much of it finding its way into coasts and waterways. Approximately 80% of marine debris is plastic (mostly bags and bottles), accumulating through spillage, runoff, dumping and discharge; with varied envi...
