The fibers have silky luster and have white appearance even in the unbleached condition. They constitute of pure cellulose and possess highest tenacity among all plant fibers. Jute: This is a versatile vegetable fiber which is biodegradable and has the ability to mix with the soil and serve as a nutrient for vegetation.

A sufficient temperature for the spinning of basalt fibers is reported to be in the range of 1350–1420°C [23]. After realizing a homogeneous melt as starting material for the spinning process, the next step is the spinning including the filament formation accompanied by the cooling and solidification of the melt.

The results showed the following: the overall performance of basalt fiber is better than that of lignin fiber. SBS modifier content in 7% can meet the requirements of drainage asphalt pavement on asphalt binder. The optimum asphalt content of SBS modified asphalt mixture with basalt fiber content of 0, 0.15, 0.25, and 0.35% is 4.9, 5.05, 5.15 ...

In order to solve the problems of the smooth surface of basalt fiber and its weak interfacial adhesion with emulsified asphalt cold recycled mixture, a silane coupling agent (KH550) was used to treat the surface of basalt fiber and the effects of treatment concentration and soaking time on fiber modification were studied. The influence of silane coupling-modified …

• High E modulus resulting in excellent specific tenacity, three times that of steel fiber_ Good fatigue resistance_ Electro-magnetic resistant Typical uses for chopped fiber strands: • Basalt is the best reinforcement for concrete due to its tensile strength and natural resistance to deterioration from alkali.

For the preparation of fibers from basalt stones, a content of silica of 46% or more is necessary. Only under this precondition it is possible to melt the stone completely without residues, to reach an adequate viscosity for fiber formation, and to gain after freezing a homogenous amorphous phase without crystalline areas [23].In general, the preparation of basalt fibers can be …
