Sesame white granite has high hardness, its Mohs hardness is about 6, its density is between 2.63g/cm3 and 2.75 g/cm3, its compaction strength is 100-300MPa, and the fine-grained granite can be as high as 300MPa or more, and its flexural strength Generally, it is 10~30Mpa. Sesame white granite is often produced in the form of rock foundation, rock strain, rock block, etc., and is controlled by the regional geography.

The general plan is relatively large and the distribution is relatively wide, so it is convenient to excavate, easy to produce large materials, and its joints are regularly developed, which is beneficial to the excavation of regular shaped stones.
