How to solve the rust problem of construction?

As we known, all metals have the natural phenomenon is Corrosion. Steel is an excellent building material which is readily available, highly recyclable and has a high strength-to-weight ratio and relatively long durability, however, it is inevitable- steel corrodes. Steel rust can reduce its strength, plasticity, toughness and other mechanical properties, will also destroy the steel geometry, shorten the service lift, thus to the buildings, bridges, roads, dyke-dams and other constructions related to steel materials to bring safety hazards. To avoid rusting problems, the steel us usually surfacing or the building is regularly repaired, which leads to the increase of production cost or maintenance cost, it is uneconomical and environmentally unfriendly.

Now a new developing, and natural 0 pollution material - basalt fiber can solve the corrosion problem. Basalt fiber is made from volcanic basalt rock by high temperature melting and bushing. Because from the natural volcanic rock and is composed of SiO2, Al2O3, CaO, MgO, TiO2, Fe2O3 and other oxides. In addition, its production process determines that it produces less waste, and the wasted product can be directly degraded in the environment without any harm. Therefore, it is a veritable green and environmentally friendly material.
Due to its stable physical and chemical properties, the basalt fiber has natural excellent performance: high-tensile strength, resists corrosion, resist rust, and resist alkali and acid, no conductive and thermal insulation. So basalt fiber can be directly used to any environment without surface treatment and without maintenance, which save a lot of money.
Take basalt rebar as an example, which is made of basalt fiber by pultrusion technology and has twice tensile strength than steel rebar and only 1/4 weight of steel rebar, and it is resist alkali and resist corrosion, in certain application, basalt rebar can replace fiberglass rebar and steel rebar.

Basalt fiber market is estimated to reach 112 Million USD in 2017. Let’s start to use the no rust material now.
