Research is being carried out on the utilization of waste products in concrete. Such waste products include discarded tires, plastic, glass, steel, burnt foundry sand, and coal combustion by-products (CCBs). Each of these waste products has provided a specific effect on the properties of fresh and hardened concrete.
The steel industry needs scrap to produce new steel, which ensures that all steel products contain anywhere from 25 percent up to 100 percent recycled content. It also is cheaper to recycle steel than it is to mine ore to manufacture new steel. New ore is still mined in order to supplement production of steel and steel products.

Utilization of blast furnace solid waste (Slag) as cement substitution material on mortar manufacture Slag is defined as a waste material produced from iron ore smelting process in blast furnace. The slag was derived from Research Center for Mineral Technology located in Tanjung Bintang Lampung Selatan with particle size of 80,100, and 120 mesh.
Recycling concrete helps reduce construction waste and extend the life of landfills as well as saving builders disposal or tipping fees. It also reduces transportation costs because concrete can often be recycled in areas near the demolition or construction site.
From iron ore to steel Steel is derived from iron. However, this metal does not exist as a pure element in nature but only in chemical compounds, for the most part in an oxygenated form. This rock-like or earthy substance is called iron ore. • Iron Ore represents – according to the mining sector – an iron content of between 30 to 70 ...

Oct 19, 2013· Due to exponential growing in urbanization and industrialization, byproducts from industries are becoming an increasing concern for recycling and waste management. Ground granulated blast furnace slag (GGBS) is by-product from the blast-furnaces of iron and steel industries. GGBS is very useful in the design and development of high-quality cement paste/mortar and concrete.
The steel is sold to plants and reused as new quality steel products. More than 65% of all reinforcing bars are recycled, according to The Steel Recycling Institute. Likewise, the concrete can be crushed and reused as aggregates in new concrete structures, in roadbeds, and for breakwaters as larger pieces.
