中国水泥及水泥基材料行业是资源密集型、能源密集型的高消耗行业,资源消耗总量非常大。2012年中国水泥产量达到21.84亿t,且仍呈增长趋势。该文以中国水泥及水泥基材料行业为研究对象,运用物质流分析方法,对该行业生产和使用中涉及的资源进行整体分析。结果显示:根据2010年数据核算,消耗石灰石资源达15.33亿t,消耗砂石资源达116.99亿t。预计到2015年,通过生料替代、砂石替代及石膏替代减少的资源消耗量总计能达到9.18亿t,较2010年进一步减少资源消耗3.74亿t。
China cement and cement-based materials industry is resource-intensive, energy-intensive high-consumption industries, the total resource consumption is very large. China’s cement output in 2012 reached 2.184 billion tons, and still showing an increasing trend. In this paper, China cement and cement-based materials industry as the research object, the use of material flow analysis method, the industry production and use of resources involved in a holistic analysis. The results show that according to the data of 2010, the consumption of limestone resources reaches 1,533 million tons and the consumption of gravel resources reaches 11,699 million tons. It is estimated that by 2015, the total amount of resource consumption reduced by raw material replacement, gravel replacement and gypsum replacement will reach 918 million tons, further reducing resource consumption by 374 million tons compared with 2010.
