How Steel Fiber Density Affects the Strength and Durability of Concrete? Concrete is one of the most widely used construction materials in the world, and its strength and durability are crucial for the success of any construction project. Steel fiber reinforced concrete (SFRC) is a type of concrete that has gained popularity in recent years due to its enhanced strength and durability compared to traditional concrete. One of the key factors that affects the strength and durability of SFRC is the density of steel fibers used in the mix.

Copper alloy is an alloy formed by adding one or several other elements to pure copper as the matrix. Pure copper is purple red in color, also known as purple copper. Pure copper has a density of 8.96 and a melting point of 1083 ℃, exhibiting excellent conductivity, thermal conductivity, ductility, and corrosion resistance. Mainly used for making electrical equipment such as generators, busbars, cables, switchgear, transformers, as well as thermal conductivity equipment such as flat plate collectors for heat exchangers, pipelines, and solar heating devices. The commonly used copper alloys are divided into three categories: brass, bronze, and white copper.

Aluminum alloy is composed of the basic element aluminum and various alloying elements, mainly copper, silicon, magnesium, etc. It is the most widely used metal material in industry, with low density, high strength, good plasticity, excellent conductivity, thermal conductivity, and corrosion resistance. It is widely used in general industry, with a usage rate second only to steel.
