What does specific gravity (γ) refer to in construction materials?

• A. The ratio of mass to volume of a material
• B. The weight per volume measurement of a material
• C. The strength of a material under tension
• D. The ability of a material to resist moisture

Answer: (B)

Specific gravity is a dimensionless quantity that indicates how dense a material is compared to water. It is defined as the ratio of the mass of the material to the mass of an equal volume of water at a specified temperature, typically 4 degrees Celsius, where water is at its maximum density. This measurement is significant in construction because it helps assess the overall weight and stability of materials when used in structures. The correct answer is that specific gravity is related to the weight per volume measurement of a material. This concept is particularly important because understanding the density and weight of construction materials affects factors such as load-bearing capabilities, material selection, and overall structural design. Accurate knowledge of specific gravity can aid engineers and architects in evaluating material performance and suitability for various applications in construction projects.
