桥梁施工往往工点分散、战线长，而且混凝土工程数量比较大，不断地提高混凝土的质量，节约原材料，降低工程造价，各施工单位应该把节约能源和提高能源的再生利用率放在首要位置上．长期以来，我段为了降低工程成本，因地制宜地试用了许多混凝土节能措施，积累了一定的经验， Bridge construction sites are often scattered, the battle line is long, and the relatively large number of concrete works, and constantly improve the quality of concrete, raw materials and reduce construction costs, the construction unit should save energy and improve energy recycling rate in the first place . For a long time, I paragraph in order to reduce the cost of construction, according to local conditions to try a lot of concrete energy-saving measures, has accumulated some experience,
