First, the use of polypropylene fibers Description:

1, structural design

Incorporation of fiber without changing the design mix concrete, reinforced concrete which is a physical effect, rather than chemistry. The addition of fiber does not affect the use of other concrete admixtures, nor any admixture from a chemical reaction with both sides using the function independently of each other.

2, mix design

Fiber in the concrete / mortar dosage ranges: 0.6 ~ 1.2kg / m3, the economic content of 0.6kg / m3, To reach a higher technical requirements, a higher dosage in the dosage range (0.9 kg / m3) (such as bridge deck and tunnel with shotcrete dosage of (1.2kg / m3); general requirements or with micro Expansive Admixture, can be a lower dosage.

3, the length of the selection

Fiber usually 6mm, 12mm two kinds of lengths. Mortar main choice 6mm, concrete choice 12mm.

4. Construction Description

Fiber is very simple to use, the equipment and construction technology stir no special requirements. Construction, according to the mix of fiber directly into the mixer, as long as an appropriate extension of the mixing time, the fibers can be used uniformly dispersed (mixing station without prolonged stirring time) in concrete.

Second, fiber applications:

A rigid self-waterproof concrete structure: basement floor, side walls, roof, roof slabs, sinks, etc.

2, interior and exterior plastering mortar: inside (outside) wall painting, day leveling the ground surface, aerated concrete, plaster and other hollow block

3, crack resistance, impact resistance, abrasion resistance, seismic requirements of the occasion: highway, bridge, airport runway, apron, ports, spillway, pier, dam panel, stadium bleachers, plant floor, long structure

4. Blast, fire occasions: air defense military engineering, oil platforms, steel mills support hob, large chimneys, towers and other Coke

5, shotcrete: subway, tunnel lining, thin-walled structures, slope reinforcement
