Jun 13, 2017 · Concrete can be recycled and reused in many ways but it all depends on how large that piece of concrete is and what is the shape of the concrete. Reusing concrete is a way to reduce your construction costs and at the same time providing some benefits to the environment when you reuse that concrete.
To establish recycling and reuse rates for steel construction products, a survey was carried out with demolition contractors in 2000. This survey was repeated in 2012. The table gives the estimates for UK steel construction products resulting from the second of these surveys.
and the generation of demolished concrete is expected to rapidly increase. We have developed a technology to produce high-quality aggregate from demolished concrete using a ‘heating and rubbing method’ (HRM) (Shima 1999, Shima 2000). Using this technology, aggregate can be recycled as raw material for ready-mixed concrete,
Cement and global warming • Making cement results in high levels of CO 2 output. • Cement production is the third ranking producer of anthropogenic (man-made) CO 2 in the world after transport and energy generation. • 4 - 5% of the worldwide total of CO 2 emissions is caused by cement production. • CO 2 is produced at two points during cement production :
