The difference between polypropylene fiber concrete and ordinary concrete

Polypropylene fiber concrete has a significant improvement in shrinkage and deformation resistance and seepage resistance compared with ordinary concrete. This

We conducted an indoor test by taking samples from the field construction,

to study the effect of different fiber mixing amount on the concrete's conventional mechanical properties,

shrinkage deformation and impermeability resistance,

and found that:

The addition of polypropylene fibers has very little effect on the concrete's conventional mechanical properties,

but it has a significant effect on the enhancement of the concrete's own resistance to shrinkage and deformation and impermeability.

The effect of polypropylene fibers on the conventional mechanical properties of concrete was found to be minimal,

but it was effective in enhancing the shrinkage deformation and impermeability of concrete.
