Recycled Plastics as Coarse Aggregate for …
Seeking aggregates for concrete and to dispose of the waste from various commodities is the present concern. Today sustainability has got top priority in construction industry. In the present study the recycled plastics were used to prepare the coarse aggregates thereby providing a sustainable option to deal with the stone waste [10]. There are many recycling plants across the world, but as ...
The Environmental Impact of Recycled Concrete
Keywords: sustainability, concrete, recycling, waste 181. 1. Introduction Concrete is a compound material many used in buildings, mainly in multi-storey buildings. Cement is a material that needs 1 to 1.5 metric ton of lime; uses a lot of energy for its production, around 4000 MJ/metric ton and releases 0.8 to 2 metric ton of carbon dioxide to the atmosphere to produce the clinker (Kumar et al ...

concrete with the addition of Electronic waste in concrete. It is found that the use of Electronic waste aggregates results in the formation of light weight concrete. In this research article Coarse aggregate is partially replaced by E- waste from 0% to 30% Then in these mix 10%, 20% and 30% of fly ash is also added by partial replacement of cement. It is thereby suggested that utilization of ...
Concrete recycling - Wikipedia
Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new concrete.Large pieces can be used as bricks or slabs, or incorporated with new concrete into structures, a material called ...
