Abstract
An organic acid material, which can be manufactured by plants extraction, encourages microbe proliferation over time. Microbial activity, which is affected by organic acid, encourages accelerating consolidation with biochemical penetration; soil particles are compacted by microbes and pore water is dissipated quickly. Additionally, $CaCO_3$ for cementation was made by proliferating microbes. Accordingly, tests were conducted to investigate the unconfined compressive strength and permeability of soil samples aged with and without an organic acid. In the 96 days of aging, the strength was generally 1.5~2.5 times greater than those without an organic acid material and permeability was definitely decreased to 74.2~93.1%. SEM analysis showed the change of pore structure and the change of the total bacteria counts revealed the activity of microbes reflecting the engineering characteristics and this material would be an environment-friendly for soil improvement.
