Production Environment
In most of construction industry, the use of concrete plays a vital part due to its durability, robustness and
cost effectiveness and thus prolongs concrete structures life. The contribution of concrete to greenhouse gas emission
and its recycling capabilities to extend its life is just one of the efforts in reducing the environmental impacts.
Since most of the raw materials in producing concrete are also sourced within the UK, this minimises the need for
transport and makes CO2 emissions very low. Also in the 1990s, the energy used in making Portland cement was reduced
by almost 25% by the cement industry in the UK which helped to decrease the use of CO2 emisions.
Ordinary composition of concrete contains about 12% cement, 8% water and 80% aggregates which includes sand,
gravel and rock; the amount of composition of aggregates can be crushed and recycled for new construction from a demolished building.
