Ultra Column Method NEO Quality Control Test
We will introduce tests to verify the appropriate water-to-binder ratio.
We would like to introduce the quality control tests for the "Ultra Column Method NEO." The "resistivity measurement of uncured improved material" is conducted to understand the mixing condition of the improved material immediately after construction by measuring its resistivity. A probe (the tip of the resistivity sensor) is attached to an SS rod and inserted into the center of the column to examine the quality of the target layer using a mixing tester (resistivity measuring device). In addition, this quality control test includes "verification of core recovery rate using boring cores," "slurry specific gravity verification," and "SS drilling." 【Test Contents】 ■ Resistivity measurement of uncured improved material ■ Verification of core recovery rate using boring cores ■ Hexavalent chromium leaching test ■ Uniaxial compression test of core specimens ■ Slurry specific gravity verification ■ Mold core sampling using a sampler ■ SS drilling *For more details, please refer to the PDF document or feel free to contact us.
