Properties of Limestone: Calcium Carbonate Content: Limestone is primarily composed of calcium carbonate (CaCO3), which gives it its fundamental chemical composition. Color: Limestone can vary in color, from white and gray to yellow, brown, and even black. The color often depends on impurities and mineral content.

This picture shows a good adhesion between the SMNAP and basalt fiber due to the surface modification conducted on SMNAP particles. Surface modification of SMNAP particles causes SMNAP particles to contribute to energy dissipation during the loading procedure. Consequently, basalt fibers break at higher levels of energy and stress.

Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill. It has a composition similar to … See more

Obsidian is an igneous rock that forms when molten rock material cools so rapidly that atoms are unable to arrange themselves into a crystalline structure. It is an amorphous material known as a " mineraloid ." The result is a volcanic glass with a smooth uniform texture that breaks with a conchoidal fracture (see photo).

5 Properties. The basalt fiber has a greenish-brown color. The physical properties and thus the areas of application are similar to those of glass fiber. Typical fiber diameters are 8–20 μm, usual lengths of the staple fibers are 0.1–100 mm. In the form of insulating wool, they are thus similar in thickness to glass fibers and very brittle.
