一、建筑工程采用高强钢筋具有显著的经济和社会效益(一)钢材生产是资源和能源消耗大户,也是污染排放大户“十一五”期间,我国钢材产量飞速增长,稳居全球第一。在所有钢材产品中,热轧带肋钢筋和线材(盘条)是主要的钢材品种,2006年~2010年,两者的年产量均超过钢材年产量的30%。据统计,我国每吨钢平均消耗1.6吨铁矿石、600公斤标准煤、4.1吨新水,排放
First, the construction of high-strength steel reinforcement has significant economic and social benefits (a) steel production is a big resource and energy consumption, but also a large polluting emissions “Eleventh Five-Year” period, the rapid growth of China’s steel production, ranking first in the world . Among all steel products, hot-rolled ribbed steel bars and wires (wire rods) are the major steel grades, with annual production exceeding 30% of annual steel production from 2006 to 2010. According to statistics, China’s average consumption of 1.6 tons of iron ore per ton, 600 kg of standard coal, 4.1 tons of new water, emissions
