polyvinyl alcohol fiber for concrete slab - TB-PVA-6S,TB-PVA-12S

Introduction

polyvinyl alcohol fiber is mainly used in sheet and section material, and could prevent the microcrack caused by the plastic shrinkage of the concrete. This environmental product gradually takes place of the asbestos and becomes a new kind of material.

Specification

Regular Spec: TB-PVA-6S,TB-PVA-12S

Note: The range of length 3-50mm, and according to your demand

Application

1. Take place of asbestos and manufacture the asbestos cement products

2. Make the light wallboard,insulation board and other building material.

3. Make the component of the concrete,tubing and board.

4. Large acreage concrete pouring, such as quay.

5. The roof,basement of the industrial and residential building.

6. The sprayed concrete, such as tunnel,mine,culvert and side slope.

Use method

1. Keep concrete the same mixing proportion, according to the designing adding quantity and the concrete volume for every mixing, weigh the fibers

2.Prepare the aggregate well, add the fibers in, then add both aggregate and fibers in the mixing machine, add water and mix.

3.After finish the mixing, fetch some as the sample, if the fibers have dispersed to monofilament, the concrete could be use for your project; if there are still bunch fibers, prolong the mixing time another 30-60 seconds.

4.The installation and protection of fiber concrete is same with common concrete

5.Adding quantity: Generally speaking, for mortar, wave tile and fiber reinforcement cement flat board, the range is 0.6-1kg/m3, common use is 0.6 kg/m³.; for concrete, the range is 0.6-1.9 kg/m³., common is 0.9 kg/m³.
