Pengaruh Perbandingan Bentonite Dan Kaolin Terhadap Kuat Geser Campuran Tanah Lempung Pasir

ABSTRACT
Sandy clay soil is a type commonly found in coastal areas and often exhibits low
shear strength, thus necessitating a study on its mechanical behavior. This research
aims to analyze the effect of varying bentonite and kaolin ratios on the shear
strength parameters of the soil, namely cohesion (c) and internal friction angle (φ),
in sandy clay soil mixtures. Soil samples were prepared based on four main
variables: sand-clay composition (75:25 and 60:40), water content (12%, 18%, and
24%), number of blows (5 and 9 blows), and the bentonite-kaolin ratio as clay
minerals. A total of 60 mixture variations were tested. All samples were then tested
using the Unconsolidated Undrained (UU) triaxial apparatus under three levels of
cell pressure (50, 100, and 150 kPa). The results showed that increasing the
proportion of bentonite in the mixture generally reduced both the cohesion and
internal friction angle values, although the effects varied depending on the water
content, soil compaction level, and sand-clay composition in the mixture.
Therefore, water content and compaction level also significantly influenced the
shear strength values of the soil. This study provides important insights into the
relationship between clay mineral composition and shear strength of sandy clay
soils under various conditions.
