The density of granite, a naturally occurring igneous rock, typically ranges from 160 to 175 pounds per cubic foot (2.56 to 2.80 grams per cubic centimeter). This density is influenced by the specific mineral composition of each granite variety. For instance, a predominantly quartz-based granite will likely be lighter than one rich in denser minerals like biotite or hornblende. Therefore, a one-cubic-foot block can vary in weight by several pounds depending on its composition. This weight is a critical factor in structural engineering and design considerations.
Understanding this material’s weight is fundamental for various applications. Historically, builders have relied on its density and durability for monumental constructions and enduring architectural elements. Today, its weight informs load-bearing calculations in modern construction, bridge building, and countertop installation. Accurately assessing this characteristic is crucial for ensuring structural integrity and safety. Furthermore, this knowledge aids in transportation logistics, estimating shipping costs, and determining appropriate handling equipment.
