砼温控费用有多种计算方法,可以扩大指标估算,也可详细计算,“概算编制简则”附表1列出的参考资料,在当时是比较详细的。随着制冷技术和骨料预冷工艺的发展,新技术不断出现,并日益成熟。例如过去是用盐水池制块冰,然后轧碎称量、掺和到砼搅拌机中。现在可在楼上直接制片状冰,可以贮藏,可以自动计量,与大型砼搅拌楼配套。再如,过去水冷骨料用的较多,近10年风冷骨料已经成熟,在长江三峡工程普遍
Concrete temperature control costs have a variety of calculation methods, you can expand the index estimates can also be calculated in detail, “budget estimates prepared ” Schedule 1 listed reference materials, was more detailed at the time. With the development of refrigeration technology and aggregate pre-cooling technology, new technologies continue to emerge and become more and more mature. For example, in the past, salt water was used to make ice pieces, crushed and weighed, and blended into concrete mixers. Now in the upstairs direct production of ice, you can store, you can automatically measure, and large concrete mixing plant supporting. Again, in the past with more water-cooled aggregate, nearly 10 years of air-cooled aggregate has matured in the Three Gorges Project is generally
