The efficient use and recycling of industrial water is a major challenge to the sustainability of the planet. Blast furnace slag is a by-product of metallurgical operations during the production of cast iron. The granulated slag is obtained by cooling in water. In this research we studied the cooling water of granulated slag generated from the process of making cast iron through the blast furnace route. The elemental analysis of granulated slag and of granulated slag stored in water was determined by X-Ray Fluores...

Waste steel slag is a major source of environmental pollution within the metallurgical industries. Metallurgical slags like blast furnace slag, ferroalloy slag, converter slag and copper slag are produced as by-products in metallurgical processes. During the production of steel, one ton of slag waste is generated per every three tons of stainless steel produced. In order to reuse waste steel slag, discharged at high temperature range (1250-1650 °C) and cooled in water, which is named as granulated slag, three diff...

This study is investigating the influences and effects of the chaotic exploitation of mineral aggregates and its direct impact on the evolutionary forms of the Siret River. The study is important due to the decommissioning of agricultural land caused by river erosion in the area of Gala?i County. After the comparative analysis of the new topographic plan with the old soil map, we identified how the area, exploited by private companies in order to extract mineral aggregates, i.e. sand and gravel mostly used in the ...

Cannabis consumption in Romania has increased significantly recently. Due to the fact that consumption is forbidden, consumers try to grow the plant themselves, in makeshift greenhouses. Cannabis is the most consumed drug in Romania, both in the general population and in the school population. Cannabis also remains the most widely seized drug nationally. Police discover at least once a month, illegal productions in apartments and confiscate hundreds of kilograms of cannabis. Only about a third of 16-year-old adole...

Environmental protection and sustainable development are two of the of great topics of interest and much concern for the new generation of passive dwelling constructors, designerпїЅs architects. In the past less concern was attached to the use of environment friendly materials in harmony with the European legislation for the construction of passive dwellings and to the questions constantly raised by life: constructors and beneficiaries should meet the legislation on these constructions in harmony with the environm...
