Mixing of steel fiber machine is the key link
Steel fiber machine is in use process, mixing is very important, determine all physical end of steel fiber
reinforced concrete properties. Therefore, we must take the scientific way of mixing tomaximum depth
of play performance of steel fiber reinforced concrete, so as to achieve and exceedthe design
requirements. In the use of steel fiber machine, no external to the manual mixingmachine mixing, two
ways. Manual mixing is generally applied in the repair engineering of small,square concrete quantity is
not always too much. So, as long as the general tried to steel fiber and concrete completely uniform
mixing can be. But the need to add steel fiber products in the process of mechanical mixing of concrete.
Mixing can be carried out in accordance with the following order:
1 the general mixing station is big is small, but the basic function is the same, so the steel fiber into
programs to be basically the same.
2 in the transmission belt, generally to pass into the hopper is dry sand, stone, at design timeproportional
to pass into the mixing bucket.
3 in the dry material adding proper amount of steel fiber (adding quantity of steel fiber according to the
design requirements, see the use ratio).
4 when the sand, stone, steel fiber are poured into the hopper, can dry mix (remember do not add water),
general dry stir for a minute to two minutes.
5 more water (the amount of water) for concrete mixing (please note the admixture of water not excessive,
otherwise easy to agglomerate steel fiber).
Loading of steel fiber cement concrete, 6 will be a good mixing, can be transported to the construction site,
use the.
7 paving process can use large machinery, can also manually pavement, the pavement with ordinary
concrete in the same.
8 pavement after compaction by vibrating compactor is required, leaving no bubbles or blisters,really want
to ensure concrete.
9 at the end of the concrete surface smooth, artificial and mechanical can. Be careful not to beexposed to
the surface of steel fiber.
