In recent years, the widespread use of polypropylene fiber project has been more and more as we know, it is becoming essential for building works in the field of building materials!

So, for the construction of large projects, the amount of polypropylene fiber works, how to control it? Xiao Bian Listen to your further analysis -

The first point:
       
Such as putty mortar cracking, permeability occasion should use smaller equivalent diameter monofilament fibers, determine a reasonable fiber length, large aspect ratio in favor of toughening effect of fiber aggregate according to particle size, the smaller length diameter ratio in favor of fiber dispersion. Putty fiber length is generally 3 mm, mortar with fibers 5-10 mm, when the diameter of 5 mm mortar sand optional fiber 12-25 mm, when up to 20 mm diameter concrete stones can be used when the 19-55 mm reticular fibers.

Second point:
       
When using fiber simultaneously added to the mixer with the aggregate, but to prevent clogging of the fiber aggregation occurs between the stirring blades and baffles. Usually stirring time is slightly prolonged, coarse aggregate is added in favor of fiber dispersion, so that the aggregate impact and elastic mesh fiber tear open to become chaotic distribution of individual fibers, but the long stirring time will affect fiber strength.

The third point:
       
Due to the addition of concrete will slump and expansion of the fibers decreases. If the slump can not meet the construction requirements, shall adopt appropriate plasticizer or superplasticizer to increase the slump to meet the construction requirements.

fourth point:
 
Construction and maintenance as ordinary concrete, no special requirements.

Fifth point:
       
Not be used as a structural material to strengthen, not replace structural reinforcement material for a separate settlement and resolve by force or impact cracking the case.
