Properties on Claystone Material Durability Kerek Formation, Semarang Regency, Central Java.
The Kerek Formation is generally composed of claystone. Claystone is identified as a unit with low
durability, while infrastructure development, especially toll roads, within the Kerek Formation is
expected to continue and expand. This research involved slake durability testing using 8 samples
from the Kerek Formation. Other properties tested included physical properties, mechanical
properties, and mineralogy, to analyze the relationship between the physical and mechanical
properties of the rock and the durability of the Kerek Formation. The research results included
correlations between durability (SDI) and the physical and mechanical properties of the rock, as
well as minerals, using a two-variable Regression Analysis. This analysis included the coefficient of
determination (R2) to indicate the impact between independent and dependent variables, the
correlation coefficient (R) to show the relationship between independent and dependent variables.
Based on the research results, it was found that in terms of the physical properties of the rock, the
moisture content had the most significant impact on slaking, with a negative regression coefficient
pattern. Meanwhile, in terms of the mechanical properties of the rock, the Direct Shear Test, which
measures the interparticle bonding or cohesion, had the most significant impact, with a positive
regression coefficient pattern. The mineral that had the most significant impact on durability was
montmorillonite, with a negative regression coefficient pattern. | en_US |
