dc.description.abstract |
Along this review, an introduction to the concrete world recycling will be done. Concrete is almost in
every building or road that is around us. As the world changes, new buildings and runways are
needed, therefore waste is generated and recycling becomes necessary. Not everybody knows
about concrete recycling for these reason people should know about it.
Concrete is the second most consumed material after water and is the basis for the urban
environment, that is why concrete waste makes up a considerable portion of the world’s waste. This
waste consists of huge amounts of materials that are often deposited without any consideration,
causing many problems and encouraging the illegal dumping. In order to avoid that, recycling
becomes really important since better opportunities are crated.
Along this review, a wide vision of recycling concrete will be shown. The main chapters are as
follows and talk about the next subjects:
[1] A brief introduction would be done into RILEM technical committees on recycling and
sustainable development. The recycling of Construction and Demolition waste has emerged as a
socioeconomic priority within the European Union and a considerable amount of research and
development has taken place in the frame of RILEM. Parallel to the work of RILEM, the recycling of
concrete has taken place in USA. American Concrete Institute has also worked on recycling of
concrete.
A short reflection is also done about the necessity of changing our habits, particularly in the building
and construction industry. The utilization of construction waste by recycling can provide
opportunities for saving energy, time, resources and money.
Collection of recovery data about recycling concrete is of more recent interest with growing concern
regarding sustainable development. Every country has its own way of quantify the amount of waste
they generate and recycle, and that is not always available in all the regions since the definitions
used vary.
Concrete recycling has many advantages as well as disadvantages. From a purely economic point of
view the recycling of building waste is only attractive when the recycled product is competitive with
natural resources in relation to cost and quality. Recycling concrete reduces natural resource
exploitation and associated transportation costs, and reduces waste landfill. As the recycling process
can be done on site it is also a way to save energy. Taking into account that this is a new technology
many people will be needed so there would be good job opportunities. |
