摘要

This study investigated suitability of kaolin clay reinforced with brick aggregate, an innovative use of construction waste, focusing on grain size distribution, Atterberg limits, specific gravity, compaction, and permeability. A modified stone column technique was introduced, employing brick aggregate column beneath kaolin through the vibro-replacement method. A uniform prototype was prepared to determine the shear strength parameters of kaolin using the Unconfined Compression Test. Two column diameters (10 mm and 16 mm) were examined across three penetration heights (60 mm, 80 mm, and 100 mm). Ratios including height-to-penetration, height-to-diameter, and volume replacement were analyzed. Strength improvements following column installation ranged from 1.07% to 16.37%. Between the two diameters tested, the 16 mm column consistently yielded higher strength gains, while the 80 mm penetration height produced the most favorable balance of stress transfer. Statistical analyses confirmed that column dimensions and ratios exerted significant influence at the 95% confidence level. Mallow’s Cp criterion verified model adequacy with minimum bias, identifying the optimum engineering model at the lowest Cp value. The criterion confirmed that the number of columns, column diameter, and penetration depth exerted substantial influence on kaolin’s strength. The findings supported the use of crushed brick in ground improvement and highlighted its environmental benefits.
