钢纤维对节能环保的社会贡献
我国目前处于建设高峰期，建设规模之大前所未有，据有关部门的统计资料，近几年城乡建设竣工面积达20亿平方米，作为建筑的主要材料，每年混凝土用量达到18亿立方米，约占全球总量的60%。
At present, China is in the peak period of construction, and the scale of construction is unprecedented. According to the statistics of relevant departments, the completed area of urban and rural construction in recent years has reached 2 billion square meters. As the main building material, the annual concrete consumption reaches 1.8 billion cubic meters, accounting for about 60% of the global total.
按照每立方混凝土平均需用水泥350公斤计，我国每年约消耗6.3亿吨水泥，每吨水泥需消耗235公斤标准煤，合计每年消耗1.5-2亿吨标准煤。中国是世界煤炭开采量和消费量最大的国家，众所周知，煤炭从开采到燃烧的每一个环节都会对环境造成破坏，但其对环境的负面影响所造成的外部成本究竟有多大呢？10月27日，绿色和平、能源基金会与世界自然基金会共同发布的《煤炭的真实成本》报告指出，2007年我国煤炭造成的环境、社会和经济等外部损失超过人民币17000亿元，相当于当年国内生产总值的7.1%。外部成本主要指煤炭在开采、运输和燃烧过车中导致的空气污染、水污染、土壤污染、生态破坏和对气候变化的加速作用等。我国每年80%的二氧化碳排放量来自燃煤。煤炭还是我国最大的空气污染源，制造了85%的二氧化硫排放量、67%的氮氧化物排放量和70%的烟尘排放量。此外，每生产一吨煤还会污染2.5吨的水。研究表明，我国煤矿每年产生的各种废污水占全国总废污水量的25%。报告的数据显示，中国每使用1吨煤，就带来150元的环境损失。其中，开采煤矿对水资源造成的永久性破坏成本达到每吨22.1元，而煤炭燃烧带来的健康成本更高达每吨44.8元。这其中还未包括煤炭燃烧排放的二氧化硫等温室气体所导致的气候变化的巨大成本。
According to the average cement requirement of 350 kilograms per cubic meter of concrete, China consumes about 630 million tons of cement every year, 235 kilograms of standard coal per ton of cement, and a total of 150-200 million tons of standard coal per year. China is the world's largest coal mining and consumption country. It is well known that every link of coal mining and combustion will cause damage to the environment, but how much is the external cost of its negative impact on the environment? On October 27, Greenpeace, Energy Foundation and WWF published the report "Real Cost of Coal" which pointed out that in 2007, China's external losses caused by coal exceeded RMB 1700 billion, equivalent to 7.1% of GDP in that year. External cost mainly refers to the air pollution, water pollution, soil pollution, ecological damage and acceleration of climate change caused by coal mining, transportation and burning. 80% of our annual carbon dioxide emissions come from coal combustion. Coal is also China's largest source of air pollution, producing 85% of sulphur dioxide emissions, 67% of nitrogen oxides emissions and 70% of smoke and dust emissions. In addition, every ton of coal produced will pollute 2.5 tons of water. Research shows that the waste water produced annually in China's coal mines accounts for 25% of the total waste water in the country. According to the report, China uses 150 tons of coal for every 1 tons of coal. Among them, the cost of permanent damage to water resources caused by coal mining is 22.1 yuan per ton, while the health cost caused by coal combustion is higher than 44.8 yuan per ton. This does not include the huge cost of climate change caused by greenhouse gases such as sulphur dioxide emitted from coal combustion.
在混凝土中应用质量、性能良好的钢纤维，能在建设中一次性减少8%-15%的水泥用量，而达到甚至部分指标超过未添加钢纤维混凝土的设计要求。应用钢纤维后使得混凝土的使用寿命大大增长，保养、维护费用大幅下降。工程质量的提高使建设社会投资的重复现象降低30%左右。综合上述因素，如在混凝土中全面推广使用钢纤维，可每年节约社会煤炭消耗量5000万吨左右，按每吨煤带来150元环境损失计，钢纤维产业的推广，能总体减少水泥用量而减少对环境造成的损失达75亿元。
The application of steel fibers with good quality and performance in concrete can reduce the cement consumption by 8%-15% at one time in construction, and reach or even exceed the design requirements of concrete without steel fibers. The use of steel fiber has greatly increased the service life of concrete, and the cost of maintenance and maintenance has been greatly reduced. The improvement of engineering quality has reduced the repetition rate of social investment by about 30%. In view of the above factors, if steel fiber is widely used in concrete, it can save about 50 million tons of social coal consumption annually. According to the environmental loss of 150 yuan per ton of coal, the promotion of steel fiber industry can reduce the total amount of cement consumption and reduce the environmental loss by 7.5 billion yuan.
