Polypropylene fiber concrete brings a different kind of youth

Polypropylene fiber is a dedicated high-performance fibers in concrete. It appears to have brought concrete life is not the same color, so they have another youth!

Why do I say this? This small series give you those things Pa Pa polypropylene fibers and concrete between ~

The reason is this thing ...... drops

First, the polypropylene fiber with a special post-production process and surface treatment can effectively increase the bond strength fiber and matrix materials, used in concrete, to prevent, reduce and delay the early plastic cracking, greatly improve the overall performance of the concrete.

Secondly, polypropylene fibers as secondary reinforcement material of concrete, can greatly improve the crack resistance, impermeability, impact, earthquake, frost, impact and abrasion resistance, anti-burst performance and ease of pumping, water retention .

Since it is so, then the following questions coming! Polypropylene fiber is how suppress concrete cracks and extend its life it?

Then things would start with the concrete it! Tensile strength of concrete in the hardening process, the hydration reaction of cement and water was caused by concrete volume shrinkage in the late and because free water evaporation caused by concrete shrinkage, the shrinkage stress beyond the cement matrix is ​​generated within the concrete microfractures. Micro-cracks develop in about 70% of the gel 3-7d period completed at this time is less than the tensile strength of concrete 1MPa.

Hush, now is the time to witness the miracle of polypropylene fibers and concrete love it! In the most critical time, not earlier, not later appeared polypropylene fibers, their fate, this started!

Join tough series of polypropylene fiber concrete in the concrete with fibers, the fibers can be easily dispersed quickly and evenly to support the formation of a chaotic system, scattered concrete orientation stress in concrete to prevent the occurrence and development of cracks in concrete natively, eliminating or reduce the number of native micro-cracks and scales, greatly improving the ability of concrete crack and leakage, improve toughness of concrete, thereby extending the life of concrete. In addition, as the fiber itself has a certain strength, fibers are uniformly dispersed in the concrete in the anchor role and form, which may absorb some of the destructive energy in an instant.

Polypropylene fibers appear in the life of the concrete, played softly role! But its effect is indeed irreplaceable!

Polypropylene fibers may also be incorporated into the mortar, to prevent, reduce and delay the micro-cracks due to the creep of a variety of factors plastic shrinkage, dehydration shrinkage, chemical shrinkage, temperature and the like due to load, which significantly improves crack mortar products , impermeability, mortar integrity, flexibility, continuity and durability can be improved.
