2、ystem as the high level, construction of large volume concrete all the time since it is the most important crucial segment in process of whole project construction. Accordingly, the construction quality that works to ensure the high level builds large volume concrete, the construction technology of
3、large volume concrete in be necessary to be built in the light of the high level undertakes study. In view of this, the article introduced the characteristic of construction of large volume concrete in high-level building and requirement, discussed the relevant content such as the construction techn
4、ology of large volume concrete mainly. 精品文档欢迎来主页查询更多精品文档,欢迎来我主页查询One high level builds the characteristic of large volume concrete in the structure to analysestructure of concrete of more average volume, large volume concrete has the characteristic of following respects: It is bulk opposite bigger,
5、and piece put oneself in anothers position is relative thicker. 2 it is concrete structure place need to be irrigated continuously build a capacity opposite bigger, and its structure is opposite also to the requirement of integral sex respect taller, for commonner concrete, the internal temperature
6、that accumulates heat of concrete to hydrate roughly to be able to bring about concrete is higher. 3 if the ply of concrete is more than 1.5m,be, the setting that must divide a construction to the level has a consideration, with reducing to hydrate better heat accumulates the bad influence that conc
7、rete structure place brings to cardinal principle. 4 it is to high-level building construction character, its accumulate concrete structure roughly to be buried at underground normally, basically use in infrastructure, the effect that consequently its suffer outside ambient temperature to change is
