Application

Fibers are distributed randomly in concrete (mortar), effectively preventing the occurrence and development of cracking, and improving the waterproof and impermeable ability.

PVA fiber for concrete (or mortar) is an ideal environmentally friendly cement reinforcement material. Due to its unique molecular structure, it has good affinity with cement, as well as good alkali and climate resistance. Adding PVA fibers to cement concrete (or mortar) can effectively control cracks caused by plastic shrinkage and temperature changes, prevent and suppress the formation and development of cracks, improve the bending strength, impact strength, and crack resistance of concrete, and effectively improve its impermeability, impact resistance, and seismic resistance. It can be widely used for wall, roof, floor, road, bridge, tunnel, and slope reinforcement in industrial and civil buildings.

Main applications:

1. Large volume concrete pouring, such as piers, high-rise building conversion beams, columns, floor slabs, etc.

2. Roof treatment, basement, and wall plastering mortar for industrial and civil buildings.

3. The pavement and guardrails of roads and bridges.

4. Concrete pouring for dams, pools, parking lots, sports fields, etc.

5. Produce concrete components, pipes, and plates.

6. Spraying concrete for tunnels, mines, culverts, slope surfaces, etc.

7. Coastal mudflat, saline alkali areas, chemical corrosion sites.

8. Replace asbestos and produce asbestos cement products.

9. Produce lightweight wall panels, GRC panels, insulation boards, and other building materials.

Features:

1. Non toxic, harmless, safe and reliable, without causing harm to the environment and construction personnel.

2. Good affinity with cement and strong grip.

3. Good dispersibility, no adhesion, easy to disperse.

4. Simple construction and cost-effective.

Usage:

1. Accurately weigh the fibers based on the designed addition amount and the volume of concrete mixed each time;

2. After preparing the sand and gravel materials, add the fibers, and then add the aggregates and fibers together to the mixer. Stir with water (you can also add the fibers to the water first, mix and disperse them, and then add them to the mixer and mix with the aggregates).

3. After mixing, random samples are taken. If the fibers have been evenly dispersed into single fibers, the concrete can be put into use. If there are still bundles of fibers, the mixing time can be extended by 30-60 seconds to use.

4. The construction and curing process of concrete with added fibers is completely the same as that of ordinary concrete.

5. Product dosage

Generally speaking, the dosage range of plain slurry or mortar, as well as fiber-reinforced cement slabs and corrugated tiles is 0.6-1kg/m, with a commonly used dosage of 0.6kg/m; Concrete, with a dosage range of 0.6-1.9kg/m. The commonly used dosage is 0. 9kg/m.
