Item Name: security protection roadway composite material manhole cover

Company introduction:

Chongqing Joywell Trade Co.,Ltd is an professional foreign trade company which was founded in 1999. We are on the market of building materials more than 14 years, obtained a good feedback both in domestic and overseas. There are kinds of steel fibers: melt extract stainless steel fiber, hooked ends cold drawn steel fiber, crimped steel fiber, cutting steel fiber, cutting micro steel fiber, copper coated steel fiber etc. Should you have any interests or suggestions, pls don’t hesitate to contact us directly.

What’s steel fiber?

Steel fibres are filaments of wire, deformed and cut to lengths, for reinforcement of concrete, mortar, cement slurry and other composite materials. They have anti-crack, anti-bend, anti-wear, anti-shear, anti-twist, anti-fatigue,stretching resistance, abrasion resistance characters. Widely be used in industry, military,construction, machinery, metallurgy, petrifaction, pottery areas.

Wide range of applications:

Highway pavements/road overlays       Airport runways and taxiways           Bridge/tunnel/mine

Composite metal decks                        Equipment foundations                    Concrete/shotcrete

Blast resistant structures                     Hydrodynamic structures                  Railway sleeper

Industrial ground floor slabs                Dam and stabilization                       Spray anchor

Commercial and residential slabs        Shock resistance structure              Cemetery/cesspool

Army construction                                Mix with refractory                           Seismic design

How to use?

1.To put steel fiber and mixing stuff into mixer to mix 30---60 seconds, the steel fiber will distribute equally in mixing stuff to avoid agglomerate.

2.Then to put sand and concrete into mixer to mix 30—60 seconds.

3.Finally to add water into the mixer to turn and mix 2-3minutes.

4.To transport them to working place.

Caution:

To minimize the risk of minor injury when handling or finishing mixes containing steel fibers, gloves should be worn. Gloves of similar quality to those normally worn by concrete placing and finishing crews are adequate. The use of gloves and eye protection during loading of steel fibers to mixer is recommended.

1.Usage:

The projects blending the concrete steel fibre with concrete in a certain ratio will evidently strengthen bending resistance, stretching resistance, abrasion resistance and pressure resistance. It is widelyused in highway, bridge, tunnel,airport runway, basic structure construction of tall building, as well as shock resistance structure and high temperature kiln stove construction.
