basaltfibers properties in general

Basaltfiber properties in general

  • low thermal conductivity (0.031-0.032)

 

  • outstanding fire resistance (Classe A1, fusione a 1160°C)

 

  • excellent breathability (µ < 1.5)

 

  • high specific heat (above 2)

 

  • remarkable mechanical resistance

 

This high-performance product confirms to be very suitable for low-thickness internal coats, for the solution of thermal bridges and for inserts in thermo-acoustic and fireproof sandwich systems.

 

Table of chopped fiber

 

Material (type of binding substance) Quantity of chopped fiber, kg Introduction result Commercial aspect Technological process
                Gypsum 0,5-0,7 % Increase of the bending resistance up to 32% without decrease of the concrete mark The decline of products cost price at the cost of a partial or complete waiving reinforcement. During the gypsum goods production process the method of a fractional  addition of chopped fiber in the finish mixture is not applicable because of increase of mixing time and , the term reduction  of gypsum  dough setting.

The method of a fractional  addition of chopped fiber in the dry mixture is preferable.

sand-cement mortar 0,3-0,6 kg (0,1-0,2 %) Increase of the compression resistance up to 70%,  the bending resistance up to 35% The decline of products cost price at the cost of a partial or complete waiving reinforcement.  The interval increase between overhauls, the increase of the products wear- ability. The decrease of cement consumption is possible, as well as a productivity gain at the cost of cutting time for the hold of a product in a form. Different methods of the chopped fiber addition  in a finish mixture are applicable.

 

The method of a fractional  addition of chopped fiber in the dry and finish mixture is preferable.

 

The chopped fiber is addicted after aggregates feeding.

The cement is added 30-45 min later chopped fiber addition.

 

Time of mixing should be limited, it should not exceed 6-10 min (depends on plasticity of mixture)

                heavy aggregate concrete 0,3 kg (4,0 %) Increase of the bending resistance up to 20% without decrease of the compression resistance, the term reduction  of cement setting The cost price reduction of products at the cost of  demand curtailment  and partial waiving reinforcement.
                foam concrete 0,3-0,6 kg (0,1-0,2 %) Increase of the compression resistance up to 80%,  the bending resistance up to 25% The decrease of cement consumption, the reduction of density with intended  strength
