Poly-Propylene Fibers (FiberCap 12)
FiberCap 12 is a Poly-Propylene Fiber that is used to control plastic shrinkage and reduce the resulting crack. Also, these fibers increase the tensile and flexural strength of concrete to some extent.
This product is produced based on the requirements of the ASTM D7508 and ASTM C1116 Standard.
The advantages of using the fibers:
The usage of the fibers
The instruction to use the fibers
The allowable range of using the fibers is between 600 to 900 g per cubic meter for ready-to-use concrete and 1 to 1.5 kg for paving and precast concrete.
The instruction to use: the aforementioned fibers are in bundles sticking to each other which should be separated by mixing and distributed in the concrete completely. It is better to add the fibers to the mixture of aggregates and cement before adding water and mixed long enough to disperse in the mixture. If the distance from batching to the site is more than 30 minutes, it is better to add the fibers gradually to the mixer at the site and mix for 10 minutes.
Note:
- The workability is improved by increasing the fibers used in the allowable range however, the consistency reduces which can be improved by using a suitable plasticizer along with this product.
- using the fibers can increase the first and final setting time of the concrete.
- It is recommended to use CapcoBond MO40 as 1% of the cement in the mix design since there is no bonding between the surface of the fibers and concrete.
