The discharge of untreated effluents into nearby water bodies or nearby land is not only aesthetically displeasing, but it also restricts light penetration, thus upsetting biological processes within a stream. In addition, many dyes are toxic to some organisms causing direct destruction of aquatic communities. Some dyes can cause allergic dermatitis, skin irrigation, cancer and mutation in man....

After the demolition of concrete structures, it is expected to recycle the whole of the demolished concrete. As of now, however, it is difficult to recycle the fine powders generated in the processes of demolition of concrete and manufacture of recycled aggregate because these powders may contain heavy metals exceeding the soil environmental standard, and such powders are disposed finally. It i...

A number of previous studies have considered the effect of the EU Emissions Trading Scheme (EU ETS) on the competitiveness of energy-intensive industrial sectors. These studies typically make theoretical predictions about product pricing, and of the profitability of European firms whose CO 2 emissions are capped, or firms which are intensive electricity users. This paper adds to the literature ...

This paper reports the preparation of sulphur polymer cements (SPCs) incorporating waste ilmenite mud for use in concrete construction works. The ilmenite mud raw material and the mud-containing SPCs (IMC-SPCs) were characterised physico-chemically and radiologically. The optimal IMC-SPC mixture had a sulphur/mud ratio (w/w) of 1.05 (mud dose 20 wt%); this cement showed the greatest compressive...

As the one of environmental-conscious concrete, equivalent for type A portland blast-furnace slag cement is due to concomitant use ordinary and B cement. In this research, considered about concrete which made accumulation weighing used these cements. results, performances were equally with Portland Moreover, influence be assumed error properties such as compressive strength development carbonat...

Porous concrete can be used as a drainage system that allows rainfall to percolate into the ground, reduce stormwater runoff, and recharge groundwater. consists of coarse aggregate cement paste. Stone mining waste in river, namely medium-sized gravel which is often called blondos stone, has not been optimally building material. Based on these reasons, it tried use stone porous concrete. Three v...
