Manufacturing costs were therefore considerably higher, but the product set reasonably slowly and developed strength quickly, thus opening up a market for use in concrete The use of concrete in construction grew rapidly from 1850 onward, and was soon the dominant use for cements Thus Portland cement began its predominant role
It requires 3 to 6 million BTUs (British thermal units) of energy and 17 tons of raw materials, mostly limestone, to make one ton of clinker Coal or coke is typically used to fire the kilns that are used to burn the limestone, clay, shale, and other materials; the ,
these sources are the principal raw materials used in the cement production process Because the production plants are expensive, the number of plants in a country is generally limited (less than 100) Carbon dioxide is emitted as a by-product of clinker production, an intermediate product in cement manufacture, in which calcium
Apr 24, 2013· World steel production in 2011 was 1518 Mt and used 761 Mt of coal – 12% of all hard coal mined The Glenbrook plant (now owned by Bluescope) makes 600-650,000 tpy steel and uses 750,000 tpy Huntly coal plus 1,000 GWh electricity and some Natural Gas, supplying 90% of NZ’s needs It also recycles steel Can we make steel with less coal?
The principal and most visible market for cement is the construction industry in a multitude of applications where it is combined with water to make concrete Most modern civil engineering projects, office buildings, apartments and domestic housing projects use concrete, often in association with steel reinforcement systems
percent to 95 percent (see Figure 5); average manhours per shipped ton have dropped from 9 hours to 3 hours during this same time frame (under 1 hour for the newest mills); and since 1950 energy consumption has declined from around 45 to 18 million Btu/ton (see Figure 6) Energy Use in the US Steel Industry 1
