The concrete of the immersed tube joint grouting concrete application of comparative example 1-4 preparations is can be seen that by the data with upper table
When admixture, inert powder, Binder Materials and water ratio change, the combination property of concrete occurred in that and significantly drop
It is low, it is difficult to meet the performance requirement of the expected immersed tube joint grouting concrete of the present invention.It can be seen that, immersed tube slip casting of the invention
Concrete has good mobility, under water not dispersed, erosion-resisting characteristics etc., and the components matching ratio with concrete has emphatically
The relation wanted, is not that the formula components of any selection adjustment concrete are capable of achieving expected effect.If using contrast
Concrete described in example 1-4 require in being difficult to meet the construction of immersed tube joint, especially for special-shaped narrow and small enclosed construction and compared with
The special circumstances used under deep water.The aspects such as the corrosion penetration for chlorion in seawater scouring, seawater can not reach engineering
It is required that rank, it is impossible to suitable for operating mode of the invention.
