发展散装水泥是一项节约资源保护环境的重要经济技术措施,对促进水泥生产、流通、使用领域经济增长方式由粗放型向集约型转变有着重要的意义。经测算,每吨散装水泥可节约包装费28元,节电7度,减少损失5%,加上人工费用综合经济效益可达45元。另外,每万吨散装水泥可节约包装用纸60吨,折合木材330立方米。同时还可提高工程建筑质量、改善工人劳动条件,推动技术进步。不仅具有显著的经济效益,而且具有重要的环境效益和社会效益。20世纪40年代,美国等世界发达国家开始发展散装水泥,用20多年的时间基本上实现了水泥的散装化,目前水泥散装率保持在90%以上。东南亚发展中国家水泥散装率也在70%左右。我国黄河三门峡水利 The development of bulk cement is an important economic and technological measure to conserve resources and protect the environment. It is of great significance to promote the transformation of the economic growth mode of cement production, circulation, and use from extensive to intensive. It has been estimated that the cost per ton of bulk cement can be reduced by 28 yuan, saving 7 degrees, reducing losses by 5%, and the overall economic benefit of labor costs can reach 45 yuan. In addition, each tons of bulk cement can save 60 tons of packaging paper, equivalent to 330 cubic meters of wood. At the same time, it can also improve the quality of construction projects, improve the working conditions of workers, and promote technological progress. Not only has significant economic benefits, but also has important environmental and social benefits. In the 1940s, the United States and other developed countries in the world began to develop bulk cement. In 20 years, cement has been basically bulk-added. The cement bulk rate is currently maintained at over 90%. The cement bulk rate in developing countries in Southeast Asia is also around 70%. China’s Yellow River Sanmenxia Water Conservancy
