STEEL FIBERS "EMCOR"

Concrete reinforced with steel fibers EMCOR is an efficient alternative to the need to strengthen and improve the structural performance of traditional concrete.The steel fiber concrete is ideal for any type of armed slab, industrial floors and other large screeds bearing capacity under extreme loads,

Effect of armed space throughout the volume of concret.
Savings in the placement phase.
Concrete volume is saved.
Personal costs are lessened since the preparation for the concreting is simpler.
It is a pumpable product.

FIBRA POLIPROPILENO

This synthetic fiber is designed to apply for structural concrete as a reinforcing material.
• Strength similar to steel.
• No rust.
• It controls a crack, impact, damage, permeability and erosion, and enhances a resisting force against several elements deteriorating concrete capacity.
