Assessing of the optimal sample size for representative measurement of laterite stone main mechanical properties
Assessing of the optimal sample size for representative measurement of laterite stone main mechanical properties
The study suggests an optimal sample size for testing and evaluating the mechanical properties of laterite stone, a natural stone commonly used in low-stress civil construction. The study found that the properties of laterite stone, such as compressive strength and elastic modulus, vary significantly depending on the sample size. Four quarries were identified, and their stones were characterized in the lab. A principal component analysis was conducted to assess the representativeness of the selected quarries. The results showed that the characteristic compression strength of laterite stone ranges from 2 to 14 MPa and the elastic modulus from 100 to 5000 MPa, depending on the sample size.
