Basalt fiber (right) compared to glass fiber (left) Basalt fibers are produced from basalt rocks by melting them and converting the melt into fibers. Basalts are rocks of igneous origin. Basalt fibers are classified into 3 types: Basalt continuous fibers (BCF), used for the production of reinforcing materials and composite products, fabrics ...
Basalt is formed by melting basalt rock; it is more cost effective than carbon, and has a good tensile strength. The drawback of basalt is when it is placed in an alkali solution, such as concrete, it loses some of its volume of fibers, thus reducing its strength.

Recently, spun basalt fiber, long available in Eastern Europe, has become available in the U.S. and Western Europe. Basalt fiber is stronger and less expensive than glass, but historically has not resisted the alkaline environment of Portland cement well enough to be used as direct reinforcement. New materials use plastic binders to isolate the ...
The tholeiitic magma series (/ ˌ θ oʊ l eɪ ˈ ɪ t ɪ k /) is one of two main magma series in subalkaline igneous rocks, the other being the calc-alkaline series. A magma series is a chemically distinct range of magma compositions that describes the evolution of a mafic magma into a more evolved, silica rich end member.
The San Francisco Giants are in agreement on a one-year, $15 million deal with starting pitcher Justin Verlander, ESPN reports. Verlander, who turns 42 in February, will join the Giants for his ...
Other readily available types of rebar are manufactured of stainless steel, and composite bars made of glass fiber, carbon fiber, or basalt fiber. The carbon steel reinforcing bars may also be coated in zinc or an epoxy resin designed to resist the effects of corrosion, especially when used in saltwater environments. Bamboo has been shown to be ...
President Donald Trump will order the U.S. to withdraw from the Paris climate agreement, the White House said on Monday, once again placing the world's top historic emitter of greenhouse gas ...
