Which of the following properties is not typically considered a primary parameter for evaluating soil as a construction material?

Tensile strength is not typically considered a primary parameter for evaluating soil as a construction material. In soil mechanics, the primary concerns involve how soil behaves under compressive loads and how it resists failure through shear. Shear strength, which measures the soil's ability to resist sliding along internal surfaces, is crucial for stability in foundation design and slope stability analyses.

Compressibility, another key parameter, assesses how much a soil will compact or change in volume under load, which is critical for understanding settlement behavior in structures. Permeability indicates how easily water can flow through soil, affecting drainage and erosion characteristics, both of which play vital roles in construction stability and performance.

In contrast, tensile strength is generally more relevant to materials like concrete and metals, where pulling forces act on the material. Soil typically fails in shear under the conditions experienced in construction, making tensile strength a less critical factor for evaluating soil suitability as a construction material.
