Concrete, as a widely used building material in civil engineering, has good mechanical properties, but with the continuous deepening of the application of engineering technology, the shortcomings of its basic mechanical properties are gradually exposed. Due to the low tensile strength characteristics of only one-tenth of the compressive strength, resulting in members of the tensile process is prone to cracking, which directly reduces the durability of the components, narrowing the scope of application of concrete materials.

At present, there are many enterprises doing research work on the large-scale production of basalt fiber, but there are still certain technical problems in production, such as the high capacity of the related units, low production efficiency, and other issues. Basalt fiber pool kiln production is a systematic project, that must continue to study and improve the corresponding supporting equipment, to solve each link to sustain development.

In the modified engineering plastics industry, long-fiber reinforced composites are composites produced from long carbon fibers, long glass fibers, aramid fibers, or basalt fibers and a polymer matrix through a series of special modification methods. The biggest feature of long fiber composites is that they have superior performance that the original material does not have.

Basalt continuous fiber is a kind of pure natural inorganic non-metallic material, which is the new material of the 21st century and one of the most important components of the new material industry. Basalt fiber is similar to glass fiber, its performance is between high strength S glass fiber and alkali-free E glass fiber, is a pure natural high-tech fiber, because the fiber color is golden brown, also known as “golden fiber”.

Basalt rebar is a revolutionary material that is gaining attention in the construction industry due to its exceptional durability and strength.   Made from basalt, this alternative to traditional steel bars offers a promising solution for building structures that require long-lasting and sustainable materials.   In this blog, we will explore the durability of basalt rebar and answer the following question: How long is the service life of basalt rebar?

Basalt fiber is a new type of inorganic environmentally friendly green high-performance fiber material, which is composed of silica, alumina, calcium oxide, magnesium oxide, iron oxide and titanium dioxide and other oxides. Basalt continuous fiber not only has high strength, but also has a variety of excellent properties such as electrical insulation, corrosion resistance, high temperature resistance and so on.

Basalt fiber through the warp knitting process made of mesh substrate, the surface coating treatment can be made of basalt fiber geogrid. Basalt geogrid is usually used for asphalt pavement reinforcement, reinforcing roadbed and soft soil base.

Basalt fiber raw material is natural basalt, basalt crushed and added to the kiln, in 1400 ~ 1500 ℃ melting, through the stretching of fibers, and the fiber as a reinforcing system into a new type of composite materials.

In today's rapid development of new material technology, basalt stone, which was once only used for paving roads, is now playing an unimaginable role.
From hard stone to light and soft fiber, basalt fiber has become an important role in the field of high-performance materials, widely used in aerospace, construction building materials, energy equipment and other high-tech fields.

Basalt fiber unidirectional cloth in the structural reinforcement of the use of performance partially meets or exceeds the carbon fiber, per square meter basalt fiber unidirectional cloth cost is 1/4-1/3 of the latter, is the most reasonable low-cost alternative to carbon fiber unidirectional cloth products.
