Unconfined Compression Test | Geoengineer
The Unconfined Compression Test is a laboratory test used to derive the Unconfirmed Compressive Strength (UCS) of a rock specimen. Unconfirmed Compressive Strength (UCS) stands for the maximum axial compressive stress that a specimen can bear under zero confining stress. Due to the fact that stress is applied along the longitudinal axis, the ...

Types of Stones used in the Construction
Basalt, sometimes known as white, green, or blue basalt, is igneous rock. This stone is good and bad for construction because it is strong and rough. This roughness makes it difficult to use the granite for any purpose. It has a specific gravity of about 3 and compressive strength of 200 to 350 N/mm2 (2039 to 3569 kg/cm2).
Properties and durability of coarse igneous rock aggregates and
Crushing strength is helpful at assessing frost durability of igneous rock aggregate. • Igneous rock aggregate with weathered minerals is freeze-thaw and alkali sensitive. • Strained quartz was the alkali reactive phase in granodiorite; chalcedony in basalt. • Alkali nepheline basalt showed best properties and durability.

Basalt Rock Properties and Uses
The rock hardness of basalt is 6 on the Mohs scale, and can be seen through a combination of its compressive strength: 100-300 Mpa (Megapascal), its tensile strength: 10-30 Mpa, and its shear strength: 20-60 Mpa, which denotes that depending on the mineral makeup, basalt rocks fall in the strong – very strong category.
