“10元钱也就是1碗面的价格。但是,如果我们通过配合比的优化,每方混凝土节约10元钱,那整个集团公司1年就要节约1个亿!”当中铁一局技术研发中心总经理在西安召开的混凝土配合比优化研讨会上说到这里,与会人员惊讶之情溢于言表。据中铁一局相关部门统计显示,中铁一局目前有在建项目280多个。从2008年至2011年,每年平均施工消耗混凝土量保守统计已超过1000万立方米。事实上,通过优化混凝土配合比而大大降低施工成本,中铁一局项目中就有着鲜活的事例。在中 “10 yuan is the price of a bowl of noodles.However, if we through the optimization of the mix, each concrete save 10 yuan, then the entire group company will save 1 million a year!” Speaking at the symposium on concrete mix optimization held in Xi’an, the general manager of R & D Center was surprised by the participants. According to statistics from relevant departments of China Railway Bureau, there are currently more than 280 projects under construction in China Railway Bureau. From 2008 to 2011, the average annual amount of construction concrete consumption statistics have been more than 10 million cubic meters. In fact, by optimizing the mix of concrete and greatly reduce the cost of construction, there is a vivid example of China Railway Bureau’s first project. In
