Cement acts as the binder between aggregates (fine and coarse rocks) in the formation of concrete. While cement makes up only a small percentage of the mix (approximately 12 percent by volume), it is almost exclusively responsible for the resulting CO 2 emissions. In the cement-manufacturing process, raw materials are heated to high temperatures in a kiln in a …

Recycling was a low-profile activity until the late 1960s, when the growing use of aluminium beverage cans brought it to public awareness. Recycling involves melting the scrap, a process that requires only 5% of the energy used to produce aluminium from ore, though a significant part (up to 15% of the input material) is lost as dross (ash-like ...
1. Introduction. Hydrous phyllosilicate clay minerals are common constituents of soils, sediments and rocks in Earth's surface environments as well as in the brittle upper crust affected by water-rock interaction (Velde, 1985; Meunier, 2005).These minerals form by diverse processes ranging from surface weathering, precipitation and accumulation in soils and sediments to …
The grade of the recovered aggregate depends on the quality of the materials collected by the recycling plants and delivered there. The manufacture of recycled aggregates is therefore difficult to achieve at an acceptable price and quality, due to the present restriction on the recycling systems.
