Steel slag is aby-product of the steel-making process, and until the 20th century, had beenlargely considered a waste material. Traditionally, they would be transportedout of the steel mills and deposited into storing yards, farmland, or siltedrivers. Eventually, the disposal options will be exhausted, necessitating thecreation of new facilities or acquisition of new land to accommodate the expandingsteel industry. It is estimated that a total of 15 tons of iron and steel slagwas produced in 2010, with production having been as high as 22 tons in 2005. Althoughsteel slag production has been recently been declining due to the lack of newconstruction activity (and therefore the idling of steel mills), the continuedmanufacture is virtually assured so long as steel remains a staple material inbuilding design.
Ferrous slagtypes have been used in the past as aggregate in asphaltic concrete roads, butdemand for steel slag has been unenthusiastic due to several factors steel slagin construction is primarily governed by the State and Federal legislatures,which have trouble gaining funding .The major funding program for slag is theTransportation Equity Act for the 21st Century (TEA-21), but the effects ofTEA-21 on slag consumption levels remained muted. Additionally,environmentally-conscious interests are more concerned with the improvement ofthe products rather than the wasted by-products .There is currently nonationwide standard for steel slag in concrete structural design.

钢渣是炼钢过程中产生的副产品,直到20世纪,在很大程度上,钢渣仍被认为是一种废料.长久以来,它们都会被运出钢铁厂,被堆填入储藏场、,农田、或被淤塞的河流里.最终,可用于处理钢渣的场所都被用尽,需要建立新的场地,或开发出新的土地来适应钢铁行业的扩张.据估计,2010年,将会生产出15吨的钢铁矿渣,早在2005年时,年产量就已高达22吨.由于最近新的建设活动有所减少,钢渣产量有所下降(并因此出现闲置的钢厂),尽管如此,实际上,只要钢材仍然是建筑设计中用到的主要材料,就必须保证钢材的继续生产.
  在过去,铁渣之类的废料已经被用作沥青混凝土道路的骨料,但钢渣的需求量一直不乐观,原因归于几个因素:钢渣工程主要是由州政府和联邦政府的立法机构管理,很难获得资金.主要的融资计划来自于《21世纪交通公平法案》,但是,该法案对于矿渣的消费水平,产生的影响微乎其微.此外,环保基金会更关心的是产品的改善,而不是那些生产废料.目前,就钢渣在混凝土结构设计中的处理方式,还未提出全国统一的标准.
