History of Electrum. This gold-silver alloy has a long history of being used by humans. It was used for different purposes since third millennium BC. However, the variation in the gold and silver contents of this alloy made it difficult to decide the value of each coin.
Malleability is the ability of materials to deform easily under compressive stress. This can be often characterized as materials ability to form thin sheets by hammering or rolling. On the other hand, Ductility is the ability of materials to deform easily under tensile stress.
These materials also possess great tensile and flexural strength. The performance of these materials is better than the normal concrete. The high fiber content bears the tensile loads, while the concrete is flexible due to the polymers. Applications of GFRC are vanity tops, wall panels, and other comparable products.
