the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Deep-sea Mining: An Emerging Marine Industry
Deep-sea mining is an emerging marine industry that presents particularly complex challenges due to its multi-faceted technological, scientific, environmental, social, industrial, political, economic and legal aspects, all of which must be addressed to achieve commercially viable results. These aspects are governed by the burgeoning regulatory regime promulgated by the International Seabed Auth...

متن کاملResilience of benthic deep-sea fauna to mining activities.
With increasing demand for mineral resources, extraction of polymetallic sulphides at hydrothermal vents, cobalt-rich ferromanganese crusts at seamounts, and polymetallic nodules on abyssal plains may be imminent. Here, we shortly introduce ecosystem characteristics of mining areas, report on recent mining developments, and identify potential stress and disturbances created by mining. We analyz...
متن کاملData Support for Modelling of Deep-Sea Mining Impacts
The paper critically reviews the presently available experimental data from various tests and experiments connected with the deepsea mining issue with regard to their feasibility in supporting and validating the developed numerical models. Numerical modelling is applied mainly to predetermining the plume development and sea oor blanketing caused by various sediment discharges. The paper describ...
