What is the unconfined compressive strength range for Type B soil?

Type B soil is classified as cohesive and generally has a higher unconfined compressive strength than Type A soils but lower than Type C soils. The unconfined compressive strength range for Type B soil is indeed more than 0.5 tsf but less than 1.5 tsf.

This classification of soil is critical in the field of construction and excavation, as it helps determine the appropriate safety measures for workers and the stability of structures. Type B soils typically have some cohesive properties but can still exhibit less strength than Type A, which is considered more stable and cohesive.

Type A soils, which have an unconfined compressive strength of 1.5 tsf or greater, are more stable and less prone to failure. Type C soils, in contrast, are granular and have less cohesive strength, often resulting in lower compressive strengths than those seen in Type B soils. Understanding these classifications is crucial for risk assessments and ensuring compliance with safety regulations in construction environments.
